+Git v1.7.10.1 Release Notes
+===========================
+
+Additions since v1.7.10
+-----------------------
+
+Localization message files for Danish and German have been added.
+
+
+Fixes since v1.7.10
+-------------------
+
+ * "git add -p" is not designed to deal with unmerged paths but did
+   not exclude them and tried to apply funny patches only to fail.
+
+ * "git blame" started missing quite a few changes from the origin
+   since we stopped using the diff minimalization by default in v1.7.2
+   era.
+
+ * When PATH contains an unreadable directory, alias expansion code
+   did not kick in, and failed with an error that said "git-subcmd"
+   was not found.
+
+ * "git clean -d -f" (not "-d -f -f") is supposed to protect nested
+   working trees of independent git repositories that exist in the
+   current project working tree from getting removed, but the
+   protection applied only to such working trees that are at the
+   top-level of the current project by mistake.
+
+ * "git commit --author=$name" did not tell the name that was being
+   recorded in the resulting commit to hooks, even though it does do
+   so when the end user overrode the authorship via the
+   "GIT_AUTHOR_NAME" environment variable.
+
+ * When "git commit --template F" errors out because the user did not
+   touch the message, it claimed that it aborts due to "empty
+   message", which was utterly wrong.
+
+ * The regexp configured with diff.wordregex was incorrectly reused
+   across files.
+
+ * An age-old corner case bug in combine diff (only triggered with -U0
+   and the hunk at the beginning of the file needs to be shown) has
+   been fixed.
+
+ * Rename detection logic used to match two empty files as renames
+   during merge-recursive, leading to unnatural mismerges.
+
+ * The parser in "fast-import" did not diagnose ":9" style references
+   that is not followed by required SP/LF as an error.
+
+ * When "git fetch" encounters repositories with too many references,
+   the command line of "fetch-pack" that is run by a helper
+   e.g. remote-curl, may fail to hold all of them. Now such an
+   internal invocation can feed the references through the standard
+   input of "fetch-pack".
+
+ * "git fetch" that recurses into submodules on demand did not check
+   if it needs to go into submodules when non branches (most notably,
+   tags) are fetched.
+
+ * "log -p --graph" used with "--stat" had a few formatting error.
+
+ * Running "notes merge --commit" failed to perform correctly when run
+   from any directory inside $GIT_DIR/.  When "notes merge" stops with
+   conflicts, $GIT_DIR/NOTES_MERGE_WORKTREE is the place a user edits
+   to resolve it.
+
+ * The 'push to upstream' implementation was broken in some corner
+   cases. "git push $there" without refspec, when the current branch
+   is set to push to a remote different from $there, used to push to
+   $there using the upstream information to a remote unreleated to
+   $there.
+
+ * Giving "--continue" to a conflicted "rebase -i" session skipped a
+   commit that only results in changes to submodules.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10.2 Release Notes
+===========================
+
+Fixes since v1.7.10.1
+---------------------
+
+ * The test scaffolding for git-daemon was flaky.
+
+ * The test scaffolding for fast-import was flaky.
+
+ * The filesystem boundary was not correctly reported when .git directory
+   discovery stopped at a mount point.
+
+ * HTTP transport that requires authentication did not work correctly when
+   multiple connections are used simultaneously.
+
+ * Minor memory leak during unpack_trees (hence "merge" and "checkout"
+   to check out another branch) has been plugged.
+
+ * In the older days, the header "Conflicts:" in "cherry-pick" and "merge"
+   was separated by a blank line from the list of paths that follow for
+   readability, but when "merge" was rewritten in C, we lost it by
+   mistake. Remove the newline from "cherry-pick" to make them match
+   again.
+
+ * The command line parser choked "git cherry-pick $name" when $name can
+   be both revision name and a pathname, even though $name can never be a
+   path in the context of the command.
+
+ * The "include.path" facility in the configuration mechanism added in
+   1.7.10 forgot to interpret "~/path" and "~user/path" as it should.
+
+ * "git config --rename-section" to rename an existing section into a
+   bogus one did not check the new name.
+
+ * The "diff --no-index" codepath used limited-length buffers, risking
+   pathnames getting truncated.  Update it to use the strbuf API.
+
+ * The report from "git fetch" said "new branch" even for a non branch
+   ref.
+
+ * The http-backend (the server side of the smart http transfer) used
+   to overwrite GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL with the
+   value obtained from REMOTE_USER unconditionally, making it
+   impossible for the server side site-specific customization to use
+   different identity sources to affect the names logged. It now uses
+   REMOTE_USER only as a fallback value.
+
+ * "log --graph" was not very friendly with "--stat" option and its
+   output had line breaks at wrong places.
+
+ * Octopus merge strategy did not reduce heads that are recorded in the
+   final commit correctly.
+
+ * "git push" over smart-http lost progress output a few releases ago;
+   this release resurrects it.
+
+ * The error and advice messages given by "git push" when it fails due
+   to non-ff were not very helpful to new users; it has been broken
+   into three cases, and each is given a separate advice message.
+
+ * The insn sheet given by "rebase -i" did not make it clear that the
+   insn lines can be re-ordered to affect the order of the commits in
+   the resulting history.
+
+ * "git repack" used to write out unreachable objects as loose objects
+   when repacking, even if such loose objects will immediately pruned
+   due to its age.
+
+ * A contrib script "rerere-train" did not work out of the box unless
+   user futzed with her $PATH.
+
+ * "git rev-parse --show-prefix" used to emit nothing when run at the
+   top-level of the working tree, but now it gives a blank line.
+
+ * The i18n of error message "git stash save" was not properly done.
+
+ * "git submodule" used a sed script that some platforms mishandled.
+
+ * When using a Perl script on a system where "perl" found on user's
+   $PATH could be ancient or otherwise broken, we allow builders to
+   specify the path to a good copy of Perl with $PERL_PATH.  The
+   gitweb test forgot to use that Perl when running its test.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10.3 Release Notes
+===========================
+
+Fixes since v1.7.10.2
+---------------------
+
+ * The message file for German translation has been updated a bit.
+
+ * Running "git checkout" on an unborn branch used to corrupt HEAD.
+
+ * When checking out another commit from an already detached state, we
+   used to report all commits that are not reachable from any of the
+   refs as lossage, but some of them might be reachable from the new
+   HEAD, and there is no need to warn about them.
+
+ * Some time ago, "git clone" lost the progress output for its
+   "checkout" phase; when run without any "--quiet" option, it should
+   give progress to the lengthy operation.
+
+ * The directory path used in "git diff --no-index", when it recurses
+   down, was broken with a recent update after v1.7.10.1 release.
+
+ * "log -z --pretty=tformat:..." did not terminate each record with
+   NUL.  The fix is not entirely correct when the output also asks for
+   --patch and/or --stat, though.
+
+ * The DWIM behaviour for "log --pretty=format:%gd -g" was somewhat
+   broken and gave undue precedence to configured log.date, causing
+   "git stash list" to show "stash@{time stamp string}".
+
+ * "git status --porcelain" ignored "--branch" option by mistake.  The
+   output for "git status --branch -z" was also incorrect and did not
+   terminate the record for the current branch name with NUL as asked.
+
+ * When a submodule repository uses alternate object store mechanism,
+   some commands that were started from the superproject did not
+   notice it and failed with "No such object" errors.  The subcommands
+   of "git submodule" command that recursed into the submodule in a
+   separate process were OK; only the ones that cheated and peeked
+   directly into the submodule's repository from the primary process
+   were affected.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.10 Release Notes
+=========================
+
+Compatibility Notes
+-------------------
+
+ * From this release on, the "git merge" command in an interactive
+   session will start an editor when it automatically resolves the
+   merge for the user to explain the resulting commit, just like the
+   "git commit" command does when it wasn't given a commit message.
+
+   If you have a script that runs "git merge" and keeps its standard
+   input and output attached to the user's terminal, and if you do not
+   want the user to explain the resulting merge commits, you can
+   export GIT_MERGE_AUTOEDIT environment variable set to "no", like
+   this:
+
+	#!/bin/sh
+	GIT_MERGE_AUTOEDIT=no
+	export GIT_MERGE_AUTOEDIT
+
+   to disable this behavior (if you want your users to explain their
+   merge commits, you do not have to do anything).  Alternatively, you
+   can give the "--no-edit" option to individual invocations of the
+   "git merge" command if you know everybody who uses your script has
+   Git v1.7.8 or newer.
+
+ * The "--binary/-b" options to "git am" have been a no-op for quite a
+   while and were deprecated in mid 2008 (v1.6.0).  When you give these
+   options to "git am", it will now warn and ask you not to use them.
+
+ * When you do not tell which branches and tags to push to the "git
+   push" command in any way, the command used "matching refs" rule to
+   update remote branches and tags with branches and tags with the
+   same name you locally have.  In future versions of Git, this will
+   change to push out only your current branch according to either the
+   "upstream" or the "current" rule.  Although "upstream" may be more
+   powerful once the user understands Git better, the semantics
+   "current" gives is simpler and easier to understand for beginners
+   and may be a safer and better default option.  We haven't decided
+   yet which one to switch to.
+
+
+Updates since v1.7.9
+--------------------
+
+UI, Workflows & Features
+
+ * various "gitk" updates.
+   - show the path to the top level directory in the window title
+   - update preference edit dialog
+   - display file list correctly when directories are given on command line
+   - make "git-describe" output in the log message into a clickable link
+   - avoid matching the UNIX timestamp part when searching all fields
+   - give preference to symbolic font names like sans & monospace
+   - allow comparing two commits using a mark
+   - "gitk" honors log.showroot configuration.
+
+ * Teams for localizing the messages from the Porcelain layer of
+   commands are starting to form, thanks to Jiang Xin who volunteered
+   to be the localization coordinator.  Translated messages for
+   simplified Chinese, Swedish and Portuguese are available.
+
+ * The configuration mechanism learned an "include" facility; an
+   assignment to the include.path pseudo-variable causes the named
+   file to be included in-place when Git looks up configuration
+   variables.
+
+ * A content filter (clean/smudge) used to be just a way to make the
+   recorded contents "more useful", and allowed to fail; a filter can
+   now optionally be marked as "required".
+
+ * Options whose names begin with "--no-" (e.g. the "--no-verify"
+   option of the "git commit" command) can be negated by omitting
+   "no-" from its name, e.g. "git commit --verify".
+
+ * "git am" learned to pass "-b" option to underlying "git mailinfo", so
+   that a bracketed string other than "PATCH" at the beginning can be kept.
+
+ * "git clone" learned "--single-branch" option to limit cloning to a
+   single branch (surprise!); tags that do not point into the history
+   of the branch are not fetched.
+
+ * "git clone" learned to detach the HEAD in the resulting repository
+   when the user specifies a tag with "--branch" (e.g., "--branch=v1.0").
+   Clone also learned to print the usual "detached HEAD" advice in such
+   a case, similar to "git checkout v1.0".
+
+ * When showing a patch while ignoring whitespace changes, the context
+   lines are taken from the postimage, in order to make it easier to
+   view the output.
+
+ * "git diff --stat" learned to adjust the width of the output on
+   wider terminals, and give more columns to pathnames as needed.
+
+ * "diff-highlight" filter (in contrib/) was updated to produce more
+   aesthetically pleasing output.
+
+ * "fsck" learned "--no-dangling" option to omit dangling object
+   information.
+
+ * "git log -G" and "git log -S" learned to pay attention to the "-i"
+   option.  With "-i", "log -G" ignores the case when finding patch
+   hunks that introduce or remove a string that matches the given
+   pattern.  Similarly with "-i", "log -S" ignores the case when
+   finding the commit the given block of text appears or disappears
+   from the file.
+
+ * "git merge" in an interactive session learned to spawn the editor
+   by default to let the user edit the auto-generated merge message,
+   to encourage people to explain their merges better. Legacy scripts
+   can export GIT_MERGE_AUTOEDIT=no to retain the historical behavior.
+   Both "git merge" and "git pull" can be given --no-edit from the
+   command line to accept the auto-generated merge message.
+
+ * The advice message given when the user didn't give enough clue on
+   what to merge to "git pull" and "git merge" has been updated to
+   be more concise and easier to understand.
+
+ * "git push" learned the "--prune" option, similar to "git fetch".
+
+ * The whole directory that houses a top-level superproject managed by
+   "git submodule" can be moved to another place.
+
+ * "git symbolic-ref" learned the "--short" option to abbreviate the
+   refname it shows unambiguously.
+
+ * "git tag --list" can be given "--points-at <object>" to limit its
+   output to those that point at the given object.
+
+ * "gitweb" allows intermediate entries in the directory hierarchy
+   that leads to a project to be clicked, which in turn shows the
+   list of projects inside that directory.
+
+ * "gitweb" learned to read various pieces of information for the
+   repositories lazily, instead of reading everything that could be
+   needed (including the ones that are not necessary for a specific
+   task).
+
+ * Project search in "gitweb" shows the substring that matched in the
+   project name and description highlighted.
+
+ * HTTP transport learned to authenticate with a proxy if needed.
+
+ * A new script "diffall" is added to contrib/; it drives an
+   external tool to perform a directory diff of two Git revisions
+   in one go, unlike "difftool" that compares one file at a time.
+
+Foreign Interface
+
+ * Improved handling of views, labels and branches in "git-p4" (in contrib).
+
+ * "git-p4" (in contrib) suffered from unnecessary merge conflicts when
+   p4 expanded the embedded $RCS$-like keywords; it can be now told to
+   unexpand them.
+
+ * Some "git-svn" updates.
+
+ * "vcs-svn"/"svn-fe" learned to read dumps with svn-deltas and
+   support incremental imports.
+
+ * "git difftool/mergetool" learned to drive DeltaWalker.
+
+Performance
+
+ * Unnecessary calls to parse_object() "git upload-pack" makes in
+   response to "git fetch", have been eliminated, to help performance
+   in repositories with excessive number of refs.
+
+Internal Implementation (please report possible regressions)
+
+ * Recursive call chains in "git index-pack" to deal with long delta
+   chains have been flattened, to reduce the stack footprint.
+
+ * Use of add_extra_ref() API is now gone, to make it possible to
+   cleanly restructure the overall refs API.
+
+ * The command line parser of "git pack-objects" now uses parse-options
+   API.
+
+ * The test suite supports the new "test_pause" helper function.
+
+ * Parallel to the test suite, there is a beginning of performance
+   benchmarking framework.
+
+ * t/Makefile is adjusted to prevent newer versions of GNU make from
+   running tests in seemingly random order.
+
+ * The code to check if a path points at a file beyond a symbolic link
+   has been restructured to be thread-safe.
+
+ * When pruning directories that has become empty during "git prune"
+   and "git prune-packed", call closedir() that iterates over a
+   directory before rmdir() it.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.9
+------------------
+
+Unless otherwise noted, all the fixes since v1.7.9 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * Build with NO_PERL_MAKEMAKER was broken and Git::I18N did not work
+   with versions of Perl older than 5.8.3.
+   (merge 5eb660e ab/perl-i18n later to maint).
+
+ * "git tag -s" honored "gpg.program" configuration variable since
+   1.7.9, but "git tag -v" and "git verify-tag" didn't.
+   (merge a2c2506 az/verify-tag-use-gpg-config later to maint).
+
+ * "configure" script learned to take "--with-sane-tool-path" from the
+   command line to record SANE_TOOL_PATH (used to avoid broken platform
+   tools in /usr/bin) in config.mak.autogen.  This may be useful for
+   people on Solaris who have saner tools outside /usr/xpg[46]/bin.
+
+ * zsh port of bash completion script needed another workaround.

+Git v1.7.11.2 Release Notes
+===========================
+
+Fixes since v1.7.11.1
+---------------------
+
+ * On Cygwin, the platform pread(2) is not thread safe, just like our
+   own compat/ emulation, and cannot be used in the index-pack
+   program.  Makefile variable NO_THREAD_SAFE_PREAD can be defined to
+   avoid use of this function in a threaded program.
+
+ * "git add" allows adding a regular file to the path where a
+   submodule used to exist, but "git update-index" does not allow an
+   equivalent operation to Porcelain writers.
+
+ * "git archive" incorrectly computed the header checksum; the symptom
+   was observed only when using pathnames with hi-bit set.
+
+ * "git blame" did not try to make sure that the abbreviated commit
+   object names in its output are unique.
+
+ * Running "git bundle verify" on a bundle that records a complete
+   history said "it requires these 0 commits".
+
+ * "git clone --single-branch" to clone a single branch did not limit
+   the cloning to the specified branch.
+
+ * "git diff --no-index" did not correctly handle relative paths and
+   did not correctly give exit codes when run under "--quiet" option.
+
+ * "git diff --no-index" did not work with pagers correctly.
+
+ * "git diff COPYING HEAD:COPYING" gave a nonsense error message that
+   claimed that the treeish HEAD did not have COPYING in it.
+
+ * When "git log" gets "--simplify-merges/by-decoration" together with
+   "--first-parent", the combination of these options makes the
+   simplification logic to use in-core commit objects that haven't
+   been examined for relevance, either producing incorrect result or
+   taking too long to produce any output.  Teach the simplification
+   logic to ignore commits that the first-parent traversal logic
+   ignored when both are in effect to work around the issue.
+
+ * "git ls-files --exclude=t -i" did not consider anything under t/ as
+   excluded, as it did not pay attention to exclusion of leading paths
+   while walking the index.  Other two users of excluded() are also
+   updated.
+
+ * "git request-pull $url dev" when the tip of "dev" branch was tagged
+   with "ext4-for-linus" used the contents from the tag in the output
+   but still asked the "dev" branch to be pulled, not the tag.
+
+Also contains minor typofixes and documentation updates.

+Git v1.7.11.3 Release Notes
+===========================
+
+Fixes since v1.7.11.3
+---------------------
+
+ * The error message from "git push $there :bogo" (and its equivalent
+   "git push $there --delete bogo") mentioned that we tried and failed
+   to guess what ref is being deleted based on the LHS of the refspec,
+   which we don't.
+
+ * A handful of files and directories we create had tighter than
+   necessary permission bits when the user wanted to have group
+   writability (e.g. by setting "umask 002").
+
+ * "commit --amend" used to refuse amending a commit with an empty log
+   message, with or without "--allow-empty-message".
+
+ * "git commit --amend --only --" was meant to allow "Clever" people to
+   rewrite the commit message without making any change even when they
+   have already changes for the next commit added to their index, but
+   it never worked as advertised since it was introduced in 1.3.0 era.
+
+ * Even though the index can record pathnames longer than 1<<12 bytes,
+   in some places we were not comparing them in full, potentially
+   replacing index entries instead of adding.
+
+ * "git show"'s auto-walking behaviour was an unreliable and
+   unpredictable hack; it now behaves just like "git log" does when it
+   walks.
+
+ * "git diff", "git status" and anything that internally uses the
+   comparison machinery was utterly broken when the difference
+   involved a file with "-" as its name.  This was due to the way "git
+   diff --no-index" was incorrectly bolted on to the system, making
+   any comparison that involves a file "-" at the root level
+   incorrectly read from the standard input.
+
+ * We did not have test to make sure "git rebase" without extra options
+   filters out an empty commit in the original history.
+
+ * "git fast-export" produced an input stream for fast-import without
+   properly quoting pathnames when they contain SPs in them.
+
+ * "git checkout --detach", when you are still on an unborn branch,
+   should be forbidden, but it wasn't.
+
+ * Some implementations of Perl terminates "lines" with CRLF even when
+   the script is operating on just a sequence of bytes.  Make sure to
+   use "$PERL_PATH", the version of Perl the user told Git to use, in
+   our tests to avoid unnecessary breakages in tests.
+
+Also contains minor typofixes and documentation updates.

+Git v1.7.11 Release Notes
+=========================
+
+Updates since v1.7.10
+---------------------
+
+UI, Workflows & Features
+
+ * A new mode for push, "simple", which is a cross between "current"
+   and "upstream", has been introduced. "git push" without any refspec
+   will push the current branch out to the same name at the remote
+   repository only when it is set to track the branch with the same
+   name over there.  The plan is to make this mode the new default
+   value when push.default is not configured.
+
+ * A couple of commands learned the "--column" option to produce
+   columnar output.
+
+ * A third-party tool "git subtree" is distributed in contrib/
+
+ * A remote helper that acts as a proxy and caches ssl session for the
+   https:// transport is added to the contrib/ area.
+
+ * Error messages given when @{u} is used for a branch without its
+   upstream configured have been clarified.
+
+ * Even with the "-q"uiet option, "checkout" used to report setting up
+   tracking.  Also "branch" learned the "-q"uiet option to squelch
+   informational message.
+
+ * Your build platform may support hardlinks but you may prefer not to
+   use them, e.g. when installing to DESTDIR to make a tarball and
+   untarring on a filesystem that has poor support for hardlinks.
+   There is a Makefile option NO_INSTALL_HARDLINKS for you.
+
+ * The smart-http backend used to always override GIT_COMMITTER_*
+   variables with REMOTE_USER and REMOTE_ADDR, but these variables are
+   now preserved when set.
+
+ * "git am" learned the "--include" option, which is an opposite of
+   existing the "--exclude" option.
+
+ * When "git am -3" needs to fall back to an application of the patch
+   to a synthesized preimage followed by a 3-way merge, the paths that
+   needed such treatment are now reported to the end user, so that the
+   result in them can be eyeballed with extra care.
+
+ * The output from "diff/log --stat" used to always allocate 4 columns
+   to show the number of modified lines, but not anymore.
+
+ * "git difftool" learned the "--dir-diff" option to spawn external
+   diff tools that can compare two directory hierarchies at a time
+   after populating two temporary directories, instead of running an
+   instance of the external tool once per a file pair.
+
+ * The "fmt-merge-msg" command learned to list the primary contributors
+   involved in the side topic you are merging in a comment in the merge
+   commit template.
+
+ * "git rebase" learned to optionally keep commits that do not
+   introduce any change in the original history.
+
+ * "git push --recurse-submodules" learned to optionally look into the
+   histories of submodules bound to the superproject and push them
+   out.
+
+ * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
+   based on the commit date.
+
+ * "gitweb" learned to highlight the patch it outputs even more.
+
+Foreign Interface
+
+ * "git svn" used to die with unwanted SIGPIPE when talking with an HTTP
+   server that uses keep-alive.
+
+ * "git svn" learned to use platform specific authentication
+   providers, e.g. gnome-keyring, kwallet, etc.
+
+ * "git p4" has been moved out of the contrib/ area and has seen more
+   work on importing labels as tags from (and exporting tags as labels
+   to) p4.
+
+Performance and Internal Implementation (please report possible regressions)
+
+ * Bash completion script (in contrib/) have been cleaned up to make
+   future work on it simpler.
+
+ * An experimental "version 4" format of the index file has been
+   introduced to reduce on-disk footprint and I/O overhead.
+
+ * "git archive" learned to produce its output without reading the
+   blob object it writes out in memory in its entirety.
+
+ * "git index-pack" that runs when fetching or pushing objects to
+   complete the packfile on the receiving end learned to use multiple
+   threads to do its job when available.
+
+ * The code to compute hash values for lines used by the internal diff
+   engine was optimized on little-endian machines, using the same
+   trick the kernel folks came up with.
+
+ * "git apply" had some memory leaks plugged.
+
+ * Setting up a revision traversal with many starting points was
+   inefficient as these were placed in a date-order priority queue
+   one-by-one.  Now they are collected in the queue unordered first,
+   and sorted immediately before getting used.
+
+ * More lower-level commands learned to use the streaming API to read
+   from the object store without keeping everything in core.
+
+ * The weighting parameters to suggestion command name typo have been
+   tweaked, so that "git tags" will suggest "tag?" and not "stage?".
+
+ * Because "sh" on the user's PATH may be utterly broken on some
+   systems, run-command API now uses SHELL_PATH, not /bin/sh, when
+   spawning an external command (not applicable to Windows port).
+
+ * The API to iterate over the refs/ hierarchy has been tweaked to
+   allow walking only a subset of it more efficiently.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.10
+-------------------
+
+Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
+releases are contained in this release (see release notes to them for
+details).
+
+ * "git submodule init" used to report "registered for path ..."
+   even for submodules that were registered earlier.
+   (cherry-pick c1c259e jl/submodule-report-new-path-once later to maint).
+
+ * "git diff --stat" used to fully count a binary file with modified
+   execution bits whose contents is unmodified, which was not quite
+   right.

+ * The date parser did not accept timezone designators that lack minutes

+
+ * After fetching from a remote that has very long refname, the reporting

+
+ * "git mergetool" did not use its arguments as pathspec, but as a path to

+
+ * "git remote rename $a $b" were not careful to match the remote name
+   against $a (i.e. source side of the remote nickname).
+
+ * "gitweb" used to produce a non-working link while showing the contents
+   of a blob, when JavaScript actions are enabled.

+Git v1.7.7.1 Release Notes
+==========================
+
+Fixes since v1.7.7
+------------------
+
+ * On some BSD systems, adding +s bit on directories is detrimental
+   (it is not necessary on BSD to begin with). "git init --shared"
+   has been updated to take this into account without extra makefile
+   settings on platforms the Makefile knows about.
+
+ * After incorrectly written third-party tools store a tag object in
+   HEAD, git diagnosed it as a repository corruption and refused to
+   proceed in order to avoid spreading the damage. We now gracefully
+   recover from such a situation by pretending as if the commit that
+   is pointed at by the tag were in HEAD.
+
+ * "git apply --whitespace=error" did not bother to report the exact
+   line number in the patch that introduced new blank lines at the end
+   of the file.
+
+ * "git apply --index" did not check corrupted patch.
+
+ * "git checkout $tree $directory/" resurrected paths locally removed or
+   modified only in the working tree in $directory/ that did not appear
+   in $directory of the given $tree. They should have been kept intact.
+
+ * "git diff $tree $path" used to apply the pathspec at the output stage,
+   reading the whole tree, wasting resources.
+
+ * The code to check for updated submodules during a "git fetch" of the
+   superproject had an unnecessary quadratic loop.
+
+ * "git fetch" from a large bundle did not enable the progress output.
+
+ * When "git fsck --lost-and-found" found that an empty blob object in the
+   object store is unreachable, it incorrectly reported an error after
+   writing the lost blob out successfully.
+
+ * "git filter-branch" did not refresh the index before checking that the
+   working tree was clean.
+
+ * "git grep $tree" when run with multiple threads had an unsafe access to
+   the object database that should have been protected with mutex.
+
+ * The "--ancestry-path" option to "git log" and friends misbehaved in a
+   history with complex criss-cross merges and showed an uninteresting
+   side history as well.
+
+ * Test t1304 assumed LOGNAME is always set, which may not be true on
+   some systems.
+
+ * Tests with --valgrind failed to find "mergetool" scriptlets.
+
+ * "git patch-id" miscomputed the patch-id in a patch that has a line longer
+   than 1kB.
+
+ * When an "exec" insn failed after modifying the index and/or the working
+   tree during "rebase -i", we now check and warn that the changes need to
+   be cleaned up.

+   "git diff | diffstat" and confusing the users.
+
+ * "git pull" and "git rebase" did not work well even when GIT_WORK_TREE is
+   set correctly with GIT_DIR if the current directory is outside the working
+   tree.
+

+Git v1.7.8.1 Release Notes
+==========================
+
+Fixes since v1.7.8
+------------------
+
+ * In some codepaths (notably, checkout and merge), the ignore patterns
+   recorded in $GIT_DIR/info/exclude were not honored. They now are.
+
+ * "git apply --check" did not error out when given an empty input
+   without any patch.
+
+ * "git archive" mistakenly allowed remote clients to ask for commits
+   that are not at the tip of any ref.
+
+ * "git checkout" and "git merge" treated in-tree .gitignore and exclude
+   file in $GIT_DIR/info/ directory inconsistently when deciding which
+   untracked files are ignored and expendable.
+
+ * LF-to-CRLF streaming filter used when checking out a large-ish blob
+   fell into an infinite loop with a rare input.
+
+ * The function header pattern for files with "diff=cpp" attribute did
+   not consider "type *funcname(type param1,..." as the beginning of a
+   function.
+
+ * The error message from "git diff" and "git status" when they fail
+   to inspect changes in submodules did not report which submodule they
+   had trouble with.
+
+ * After fetching from a remote that has very long refname, the reporting
+   output could have corrupted by overrunning a static buffer.
+
+ * "git pack-objects" avoids creating cyclic dependencies among deltas
+   when seeing a broken packfile that records the same object in both
+   the deflated form and as a delta.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.8.2 Release Notes
+==========================
+
+Fixes since v1.7.8.1
+--------------------
+
+ * Porcelain commands like "git reset" did not distinguish deletions
+   and type-changes from ordinary modification, and reported them with
+   the same 'M' moniker. They now use 'D' (for deletion) and 'T' (for
+   type-change) to match "git status -s" and "git diff --name-status".
+
+ * The configuration file parser used for sizes (e.g. bigFileThreshold)
+   did not correctly interpret 'g' suffix.
+
+ * The replacement implemention for snprintf used on platforms with
+   native snprintf that is broken did not use va_copy correctly.
+
+ * LF-to-CRLF streaming filter replaced all LF with CRLF, which might
+   be techinically correct but not friendly to people who are trying
+   to recover from earlier mistakes of using CRLF in the repository
+   data in the first place. It now refrains from doing so for LF that
+   follows a CR.
+
+ * git native connection going over TCP (not over SSH) did not set
+   SO_KEEPALIVE option which failed to receive link layer errors.
+
+ * "git branch -m <current branch> HEAD" is an obvious no-op but was not
+   allowed.
+
+ * "git checkout -m" did not recreate the conflicted state in a "both
+   sides added, without any common ancestor version" conflict
+   situation.
+
+ * "git cherry-pick $commit" (not a range) created an unnecessary
+   sequencer state and interfered with valid workflow to use the
+   command during a session to cherry-pick multiple commits.
+
+ * You could make "git commit" segfault by giving the "--no-message"
+   option.
+
+ * "fast-import" did not correctly update an existing notes tree,
+   possibly corrupting the fan-out.
+
+ * "git fetch-pack" accepted unqualified refs that do not begin with
+   refs/ by mistake and compensated it by matching the refspec with
+   tail-match, which was doubly wrong. This broke fetching from a
+   repository with a funny named ref "refs/foo/refs/heads/master" and a
+   'master' branch with "git fetch-pack refs/heads/master", as the
+   command incorrectly considered the former a "match".
+
+ * "git log --follow" did not honor the rename threshold score given
+   with the -M option (e.g. "-M50%").
+
+ * "git mv" gave suboptimal error/warning messages when it overwrites
+   target files. It also did not pay attention to "-v" option.
+
+ * Authenticated "git push" over dumb HTTP were broken with a recent
+   change and failed without asking for password when username is
+   given.
+
+ * "git push" to an empty repository over HTTP were broken with a
+   recent change to the ref handling.
+
+ * "git push -v" forgot how to be verbose by mistake. It now properly
+   becomes verbose when asked to.
+
+ * When a "reword" action in "git rebase -i" failed to run "commit --amend",
+   we did not give the control back to the user to resolve the situation, and
+   instead kept the original commit log message.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.8 Release Notes
+========================
+
+Updates since v1.7.7
+--------------------
+
+ * Some git-svn, git-gui, git-p4 (in contrib) and msysgit updates.
+
+ * Updates to bash completion scripts.
+
+ * The build procedure has been taught to take advantage of computed
+   dependency automatically when the complier supports it.
+
+ * The date parser now accepts timezone designators that lack minutes
+   part and also has a colon between "hh:mm".
+
+ * The contents of the /etc/mailname file, if exists, is used as the
+   default value of the hostname part of the committer/author e-mail.
+
+ * "git am" learned how to read from patches generated by Hg.
+
+ * "git archive" talking with a remote repository can report errors
+   from the remote side in a more informative way.
+
+ * "git branch" learned an explicit --list option to ask for branches
+   listed, optionally with a glob matching pattern to limit its output.
+
+ * "git check-attr" learned "--cached" option to look at .gitattributes
+   files from the index, not from the working tree.
+
+ * Variants of "git cherry-pick" and "git revert" that take multiple
+   commits learned to "--continue" and "--abort".
+
+ * "git daemon" gives more human readble error messages to clients
+   using ERR packets when appropriate.
+
+ * Errors at the network layer is logged by "git daemon".
+
+ * "git diff" learned "--minimal" option to spend extra cycles to come
+   up with a minimal patch output.
+
+ * "git diff" learned "--function-context" option to show the whole
+   function as context that was affected by a change.
+
+ * "git difftool" can be told to skip launching the tool for a path by
+   answering 'n' to its prompt.
+
+ * "git fetch" learned to honor transfer.fsckobjects configuration to
+   validate the objects that were received from the other end, just like
+   "git receive-pack" (the receiving end of "git push") does.
+
+ * "git fetch" makes sure that the set of objects it received from the
+   other end actually completes the history before updating the refs.
+   "git receive-pack" (the receiving end of "git push") learned to do the
+   same.
+
+ * "git fetch" learned that fetching/cloning from a regular file on the
+   filesystem is not necessarily a request to unpack a bundle file; the
+   file could be ".git" with "gitdir: <path>" in it.
+
+ * "git for-each-ref" learned "%(contents:subject)", "%(contents:body)"
+   and "%(contents:signature)". The last one is useful for signed tags.
+
+ * "git grep" used to incorrectly pay attention to .gitignore files
+   scattered in the directory it was working in even when "--no-index"
+   option was used. It no longer does this. The "--exclude-standard"
+   option needs to be given to explicitly activate the ignore
+   mechanism.
+
+ * "git grep" learned "--untracked" option, where given patterns are
+    searched in untracked (but not ignored) files as well as tracked
+    files in the working tree, so that matches in new but not yet
+    added files do not get missed.
+
+ * The recursive merge backend no longer looks for meaningless
+   existing merges in submodules unless in the outermost merge.
+
+ * "git log" and friends learned "--children" option.
+
+ * "git ls-remote" learned to respond to "-h"(elp) requests.
+
+ * "mediawiki" remote helper can interact with (surprise!) MediaWiki
+   with "git fetch" & "git push".
+
+ * "git merge" learned the "--edit" option to allow users to edit the
+   merge commit log message.
+
+ * "git rebase -i" can be told to use special purpose editor suitable
+   only for its insn sheet via sequence.editor configuration variable.
+
+ * "git send-email" learned to respond to "-h"(elp) requests.
+
+ * "git send-email" allows the value given to sendemail.aliasfile to begin
+   with "~/" to refer to the $HOME directory.
+
+ * "git send-email" forces use of Authen::SASL::Perl to work around
+   issues between Authen::SASL::Cyrus and AUTH PLAIN/LOGIN.
+
+ * "git stash" learned "--include-untracked" option to stash away
+   untracked/ignored cruft from the working tree.
+
+ * "git submodule clone" does not leak an error message to the UI
+   level unnecessarily anymore.
+
+ * "git submodule update" learned to honor "none" as the value for
+   submodule.<name>.update to specify that the named submodule should
+   not be checked out by default.
+
+ * When populating a new submodule directory with "git submodule init",
+   the $GIT_DIR metainformation directory for submodules is created inside
+   $GIT_DIR/modules/<name>/ directory of the superproject and referenced
+   via the gitfile mechanism. This is to make it possible to switch
+   between commits in the superproject that has and does not have the
+   submodule in the tree without re-cloning.
+
+ * "gitweb" leaked unescaped control characters from syntax hiliter
+   outputs.
+
+ * "gitweb" can be told to give custom string at the end of the HTML
+   HEAD element.
+
+ * "gitweb" now has its own manual pages.
+
+
+Also contains other documentation updates and minor code cleanups.
+
+
+Fixes since v1.7.7
+------------------
+
+Unless otherwise noted, all fixes in the 1.7.7.X maintenance track are
+included in this release.
+
+ * HTTP transport did not use pushurl correctly, and also did not tell
+   what host it is trying to authenticate with when asking for
+   credentials.
+   (merge deba493 jk/http-auth later to maint).
+
+ * "git blame" was aborted if started from an uncommitted content and
+   the path had the textconv filter in effect.
+   (merge 8518088 ss/blame-textconv-fake-working-tree later to maint).
+
+ * Adding many refs to the local repository in one go (e.g. "git fetch"
+   that fetches many tags) and looking up a ref by name in a repository
+   with too many refs were unnecessarily slow.
+   (merge 17d68a54d jp/get-ref-dir-unsorted later to maint).
+
+ * Report from "git commit" on untracked files was confused under
+   core.ignorecase option.
+   (merge 395c7356 jk/name-hash-dirent later to maint).
+
+ * "git merge" did not understand ":/<pattern>" as a way to name a commit.
+
+ " "git push" on the receiving end used to call post-receive and post-update
+   hooks for attempted removal of non-existing refs.
+   (merge 160b81ed ph/push-to-delete-nothing later to maint).
+
+ * Help text for "git remote set-url" and "git remote set-branches"
+   were misspelled.
+   (merge c49904e fc/remote-seturl-usage-fix later to maint).
+   (merge 656cdf0 jc/remote-setbranches-usage-fix later to maint).

+Git v1.7.9.1 Release Notes
+==========================
+
+Fixes since v1.7.9
+------------------
+
+ * The makefile allowed environment variable X seep into it result in
+   command names suffixed with unnecessary strings.
+
+ * The set of included header files in compat/inet-{ntop,pton}
+   wrappers was updated for Windows some time ago, but in a way that
+   broke Solaris build.
+
+ * rpmbuild noticed an unpackaged but installed *.mo file and failed.
+
+ * Subprocesses spawned from various git programs were often left running
+   to completion even when the top-level process was killed.
+
+ * "git add -e" learned not to show a diff for an otherwise unmodified
+   submodule that only has uncommitted local changes in the patch
+   prepared by for the user to edit.
+
+ * Typo in "git branch --edit-description my-tpoic" was not diagnosed.
+
+ * Using "git grep -l/-L" together with options -W or --break may not
+   make much sense as the output is to only count the number of hits
+   and there is no place for file breaks, but the latter options made
+   "-l/-L" to miscount the hits.
+
+ * "git log --first-parent $pathspec" did not stay on the first parent
+   chain and veered into side branch from which the whole change to the
+   specified paths came.
+
+ * "git merge --no-edit $tag" failed to honor the --no-edit option.
+
+ * "git merge --ff-only $tag" failed because it cannot record the
+   required mergetag without creating a merge, but this is so common
+   operation for branch that is used _only_ to follow the upstream, so
+   it was changed to allow fast-forwarding without recording the mergetag.
+
+ * "git mergetool" now gives an empty file as the common base version
+   to the backend when dealing with the "both sides added, differently"
+   case.
+
+ * "git push -q" was not sufficiently quiet.
+
+ * When "git push" fails to update any refs, the client side did not
+   report an error correctly to the end user.
+
+ * "rebase" and "commit --amend" failed to work on commits with ancient
+   timestamps near year 1970.
+
+ * When asking for a tag to be pulled, "request-pull" did not show the
+   name of the tag prefixed with "tags/", which would have helped older
+   clients.
+
+ * "git submodule add $path" forgot to recompute the name to be stored
+   in .gitmodules when the submodule at $path was once added to the
+   superproject and already initialized.
+
+ * Many small corner case bugs on "git tag -n" was corrected.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.9.2 Release Notes
+==========================
+
+Fixes since v1.7.9.1
+--------------------
+
+ * Bash completion script (in contrib/) did not like a pattern that
+   begins with a dash to be passed to __git_ps1 helper function.
+
+ * Adaptation of the bash completion script (in contrib/) for zsh
+   incorrectly listed all subcommands when "git <TAB><TAB>" was given
+   to ask for list of porcelain subcommands.
+
+ * The build procedure for profile-directed optimized binary was not
+   working very well.
+
+ * Some systems need to explicitly link -lcharset to get locale_charset().
+
+ * t5541 ignored user-supplied port number used for HTTP server testing.
+
+ * The error message emitted when we see an empty loose object was
+   not phrased correctly.
+
+ * The code to ask for password did not fall back to the terminal
+   input when GIT_ASKPASS is set but does not work (e.g. lack of X
+   with GUI askpass helper).
+
+ * We failed to give the true terminal width to any subcommand when
+   they are invoked with the pager, i.e. "git -p cmd".
+
+ * map_user() was not rewriting its output correctly, which resulted
+   in the user visible symptom that "git blame -e" sometimes showed
+   excess '>' at the end of email addresses.
+
+ * "git checkout -b" did not allow switching out of an unborn branch.
+
+ * When you have both .../foo and .../foo.git, "git clone .../foo" did not
+   favor the former but the latter.
+
+ * "git commit" refused to create a commit when entries added with
+   "add -N" remained in the index, without telling Git what their content
+   in the next commit should be. We should have created the commit without
+   these paths.
+
+ * "git diff --stat" said "files", "insertions", and "deletions" even
+   when it is showing one "file", one "insertion" or one "deletion".
+
+ * The output from "git diff --stat" for two paths that have the same
+   amount of changes showed graph bars of different length due to the
+   way we handled rounding errors.
+
+ * "git grep" did not pay attention to -diff (hence -binary) attribute.
+
+ * The transport programs (fetch, push, clone)ignored --no-progress
+   and showed progress when sending their output to a terminal.
+
+ * Sometimes error status detected by a check in an earlier phase of
+   "git receive-pack" (the other end of "git push") was lost by later
+   checks, resulting in false indication of success.
+
+ * "git rev-list --verify" sometimes skipped verification depending on
+   the phase of the moon, which dates back to 1.7.8.x series.
+
+ * Search box in "gitweb" did not accept non-ASCII characters correctly.
+
+ * Search interface of "gitweb" did not show multiple matches in the same file
+   correctly.
+
+Also contains minor fixes and documentation updates.

+
+ * The config.mak.autogen generated by optional autoconf support tried
+   to link the binary with -lintl even when libintl.h is missing from
+   the system.
+
+ * When the filter driver exits before reading the content before the
+   main git process writes the contents to be filtered to the pipe to
+   it, the latter could be killed with SIGPIPE instead of ignoring
+   such an event as an error.
+
+ * "git add --refresh <pathspec>" used to warn about unmerged paths
+   outside the given pathspec.
+
+ * The bulk check-in codepath in "git add" streamed contents that
+   needs smudge/clean filters without running them, instead of punting
+   and delegating to the codepath to run filters after slurping
+   everything to core.
+
+ * "git branch --with $that" assumed incorrectly that the user will never
+   ask the question with nonsense value in $that.
+
+ * "git bundle create" produced a corrupt bundle file upon seeing
+   commits with excessively long subject line.
+
+ * When a remote helper exits before reading the blank line from the

+Git v1.7.9.4 Release Notes
+==========================
+
+Fixes since v1.7.9.3
+--------------------
+
+ * The code to synthesize the fake ancestor tree used by 3-way merge
+   fallback in "git am" was not prepared to read a patch created with
+   a non-standard -p<num> value.
+
+ * "git bundle" did not record boundary commits correctly when there
+   are many of them.
+
+ * "git diff-index" and its friends at the plumbing level showed the
+   "diff --git" header and nothing else for a path whose cached stat
+   info is dirty without actual difference when asked to produce a
+   patch. This was a longstanding bug that we could have fixed long
+   time ago.
+
+ * "gitweb" did use quotemeta() to prepare search string when asked to
+   do a fixed-string project search, but did not use it by mistake and
+   used the user-supplied string instead.
+
+Also contains minor fixes and documentation updates.

+Git v1.7.9 Release Notes
+========================
+
+Updates since v1.7.8
+--------------------
+
+ * gitk updates accumulated since early 2011.
+
+ * git-gui updated to 0.16.0.
+
+ * git-p4 (in contrib/) updates.
+
+ * Git uses gettext to translate its most common interface messages
+   into the user's language if translations are available and the
+   locale is appropriately set. Distributors can drop new PO files
+   in po/ to add new translations.
+
+ * The code to handle username/password for HTTP transactions used in
+   "git push" & "git fetch" learned to talk "credential API" to
+   external programs to cache or store them, to allow integration with
+   platform native keychain mechanisms.
+
+ * The input prompts in the terminal use our own getpass() replacement
+   when possible. HTTP transactions used to ask for the username without
+   echoing back what was typed, but with this change you will see it as
+   you type.
+
+ * The internals of "revert/cherry-pick" have been tweaked to prepare
+   building more generic "sequencer" on top of the implementation that
+   drives them.
+
+ * "git rev-parse FETCH_HEAD" after "git fetch" without specifying
+   what to fetch from the command line will now show the commit that
+   would be merged if the command were "git pull".
+
+ * "git add" learned to stream large files directly into a packfile
+   instead of writing them into individual loose object files.
+
+ * "git checkout -B <current branch> <elsewhere>" is a more intuitive
+   way to spell "git reset --keep <elsewhere>".
+
+ * "git checkout" and "git merge" learned "--no-overwrite-ignore" option
+   to tell Git that untracked and ignored files are not expendable.
+
+ * "git commit --amend" learned "--no-edit" option to say that the
+   user is amending the tree being recorded, without updating the
+   commit log message.
+
+ * "git commit" and "git reset" re-learned the optimization to prime
+   the cache-tree information in the index, which makes it faster to
+   write a tree object out after the index entries are updated.
+
+ * "git commit" detects and rejects an attempt to stuff NUL byte in
+   the commit log message.
+
+ * "git commit" learned "-S" to GPG-sign the commit; this can be shown
+   with the "--show-signature" option to "git log".
+
+ * fsck and prune are relatively lengthy operations that still go
+   silent while making the end-user wait. They learned to give progress
+   output like other slow operations.
+
+ * The set of built-in function-header patterns for various languages
+   knows MATLAB.
+
+ * "git log --format='<format>'" learned new %g[nNeE] specifiers to
+   show information from the reflog entries when walking the reflog
+   (i.e. with "-g").
+
+ * "git pull" can be used to fetch and merge an annotated/signed tag,
+   instead of the tip of a topic branch. The GPG signature from the
+   signed tag is recorded in the resulting merge commit for later
+   auditing.
+
+ * "git log" learned "--show-signature" option to show the signed tag
+   that was merged that is embedded in the merge commit. It also can
+   show the signature made on the commit with "git commit -S".
+
+ * "git branch --edit-description" can be used to add descriptive text
+   to explain what a topic branch is about.
+
+ * "git fmt-merge-msg" learned to take the branch description into
+   account when preparing a merge summary that "git merge" records
+   when merging a local branch.
+
+ * "git request-pull" has been updated to convey more information
+   useful for integrators to decide if a topic is worth merging and
+   what is pulled is indeed what the requestor asked to pull,
+   including:
+
+   - the tip of the branch being requested to be merged;
+   - the branch description describing what the topic is about;
+   - the contents of the annotated tag, when requesting to pull a tag.
+
+ * "git pull" learned to notice 'pull.rebase' configuration variable,
+   which serves as a global fallback for setting 'branch.<name>.rebase'
+   configuration variable per branch.
+
+ * "git tag" learned "--cleanup" option to control how the whitespaces
+   and empty lines in tag message are cleaned up.
+
+ * "gitweb" learned to show side-by-side diff.
+
+Also contains minor documentation updates and code clean-ups.
+
+
+Fixes since v1.7.8
+------------------

+Unless otherwise noted, all the fixes since v1.7.8 in the maintenance
+releases are contained in this release (see release notes to them for

+=======================
+
+NAME
+----
+git-credential-cache - helper to temporarily store passwords in memory
+
+SYNOPSIS
+--------
+-----------------------------
+git config credential.helper 'cache [options]'
+-----------------------------
+
+DESCRIPTION
+-----------
+
+This command caches credentials in memory for use by future git
+programs. The stored credentials never touch the disk, and are forgotten
+after a configurable timeout.  The cache is accessible over a Unix
+domain socket, restricted to the current user by filesystem permissions.
+
+You probably don't want to invoke this command directly; it is meant to
+be used as a credential helper by other parts of git. See
+linkgit:gitcredentials[7] or `EXAMPLES` below.
+
+OPTIONS
+-------
+
+--timeout <seconds>::
+
+	Number of seconds to cache credentials (default: 900).
+
+--socket <path>::
+
+	Use `<path>` to contact a running cache daemon (or start a new
+	cache daemon if one is not started). Defaults to
+	`~/.git-credential-cache/socket`. If your home directory is on a
+	network-mounted filesystem, you may need to change this to a
+	local filesystem.
+
+CONTROLLING THE DAEMON
+----------------------
+
+If you would like the daemon to exit early, forgetting all cached
+credentials before their timeout, you can issue an `exit` action:
+
+--------------------------------------
+git credential-cache exit
+--------------------------------------
+
+EXAMPLES
+--------
+
+The point of this helper is to reduce the number of times you must type
+your username or password. For example:
+
+------------------------------------
+$ git config credential.helper cache
+$ git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+
+[work for 5 more minutes]
+$ git push http://example.com/repo.git
+[your credentials are used automatically]
+------------------------------------
+
+You can provide options via the credential.helper configuration
+variable (this example drops the cache time to 5 minutes):

+$ git config credential.helper 'cache --timeout=300'

+NAME
+----
+git-credential-store - helper to store credentials on disk
+
+SYNOPSIS
+--------
+-------------------
+git config credential.helper 'store [options]'
+-------------------
+
+DESCRIPTION
+-----------
+
+NOTE: Using this helper will store your passwords unencrypted on disk,
+protected only by filesystem permissions. If this is not an acceptable
+security tradeoff, try linkgit:git-credential-cache[1], or find a helper
+that integrates with secure storage provided by your operating system.
+
+This command stores credentials indefinitely on disk for use by future
+git programs.
+
+You probably don't want to invoke this command directly; it is meant to
+be used as a credential helper by other parts of git. See
+linkgit:gitcredentials[7] or `EXAMPLES` below.
+
+OPTIONS
+-------
+
+--store=<path>::
+
+	Use `<path>` to store credentials. The file will have its
+	filesystem permissions set to prevent other users on the system
+	from reading it, but will not be encrypted or otherwise
+	protected. Defaults to `~/.git-credentials`.
+
+EXAMPLES
+--------
+
+The point of this helper is to reduce the number of times you must type
+your username or password. For example:
+
+------------------------------------------
+$ git config credential.helper store
+$ git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+
+[several days later]
+$ git push http://example.com/repo.git
+[your credentials are used automatically]
+------------------------------------------
+
+STORAGE FORMAT
+--------------
+
+The `.git-credentials` file is stored in plaintext. Each credential is
+stored on its own line as a URL like:
+
+------------------------------
+https://user:pass@example.com
+------------------------------
+
+When git needs authentication for a particular URL context,
+credential-store will consider that context a pattern to match against
+each entry in the credentials file.  If the protocol, hostname, and
+username (if we already have one) match, then the password is returned
+to git. See the discussion of configuration in linkgit:gitcredentials[7]
+for more information.

+Responses To Commands
+---------------------
+New objects written by fast-import are not available immediately.
+Most fast-import commands have no visible effect until the next
+checkpoint (or completion).  The frontend can send commands to
+fill fast-import's input pipe without worrying about how quickly
+they will take effect, which improves performance by simplifying
+scheduling.
+
+For some frontends, though, it is useful to be able to read back
+data from the current repository as it is being updated (for
+example when the source material describes objects in terms of
+patches to be applied to previously imported objects).  This can
+be accomplished by connecting the frontend and fast-import via
+bidirectional pipes:
+
+====
+	mkfifo fast-import-output
+	frontend <fast-import-output |
+	git fast-import >fast-import-output
+====
+
+A frontend set up this way can use `progress`, `ls`, and `cat-blob`
+commands to read information from the import in progress.
+
+To avoid deadlock, such frontends must completely consume any
+pending output from `progress`, `ls`, and `cat-blob` before
+performing writes to fast-import that might block.

+git-p4 - Import from and submit to Perforce repositories
+

+SYNOPSIS

+[verse]
+'git p4 clone' [<sync options>] [<clone options>] <p4 depot path>...
+'git p4 sync' [<sync options>] [<p4 depot path>...]
+'git p4 rebase'

+
+
+DESCRIPTION
+-----------
+This command provides a way to interact with p4 repositories
+using git.
+
+Create a new git repository from an existing p4 repository using
+'git p4 clone', giving it one or more p4 depot paths.  Incorporate
+new commits from p4 changes with 'git p4 sync'.  The 'sync' command
+is also used to include new branches from other p4 depot paths.
+Submit git changes back to p4 using 'git p4 submit'.  The command
+'git p4 rebase' does a sync plus rebases the current branch onto
+the updated p4 remote branch.
+
+
+EXAMPLE
+-------
+* Clone a repository:
++
+------------
+$ git p4 clone //depot/path/project
+------------
+
+* Do some work in the newly created git repository:
++
+------------
+$ cd project
+$ vi foo.h
+$ git commit -a -m "edited foo.h"
+------------
+
+* Update the git repository with recent changes from p4, rebasing your
+  work on top:
++
+------------
+$ git p4 rebase
+------------
+
+* Submit your commits back to p4:
++
+------------
+$ git p4 submit
+------------
+
+
+COMMANDS
+--------
+
+Clone
+~~~~~
+Generally, 'git p4 clone' is used to create a new git directory
+from an existing p4 repository:
+------------
+$ git p4 clone //depot/path/project
+------------
+This:
+
+1.   Creates an empty git repository in a subdirectory called 'project'.
++
+2.   Imports the full contents of the head revision from the given p4
+depot path into a single commit in the git branch 'refs/remotes/p4/master'.
++
+3.   Creates a local branch, 'master' from this remote and checks it out.
+
+To reproduce the entire p4 history in git, use the '@all' modifier on
+the depot path:
+------------
+$ git p4 clone //depot/path/project@all
+------------
+
+
+Sync
+~~~~
+As development continues in the p4 repository, those changes can
+be included in the git repository using:
+------------
+$ git p4 sync
+------------
+This command finds new changes in p4 and imports them as git commits.
+
+P4 repositories can be added to an existing git repository using
+'git p4 sync' too:
+------------
+$ mkdir repo-git
+$ cd repo-git
+$ git init
+$ git p4 sync //path/in/your/perforce/depot
+------------
+This imports the specified depot into
+'refs/remotes/p4/master' in an existing git repository.  The
+'--branch' option can be used to specify a different branch to
+be used for the p4 content.
+
+If a git repository includes branches 'refs/remotes/origin/p4', these
+will be fetched and consulted first during a 'git p4 sync'.  Since
+importing directly from p4 is considerably slower than pulling changes
+from a git remote, this can be useful in a multi-developer environment.
+
+
+Rebase
+~~~~~~
+A common working pattern is to fetch the latest changes from the p4 depot
+and merge them with local uncommitted changes.  Often, the p4 repository
+is the ultimate location for all code, thus a rebase workflow makes
+sense.  This command does 'git p4 sync' followed by 'git rebase' to move
+local commits on top of updated p4 changes.
+------------
+$ git p4 rebase
+------------
+
+
+Submit
+~~~~~~
+Submitting changes from a git repository back to the p4 repository
+requires a separate p4 client workspace.  This should be specified
+using the 'P4CLIENT' environment variable or the git configuration
+variable 'git-p4.client'.  The p4 client must exist, but the client root
+will be created and populated if it does not already exist.
+
+To submit all changes that are in the current git branch but not in
+the 'p4/master' branch, use:
+------------
+$ git p4 submit
+------------
+
+To specify a branch other than the current one, use:
+------------
+$ git p4 submit topicbranch
+------------
+
+The upstream reference is generally 'refs/remotes/p4/master', but can
+be overridden using the '--origin=' command-line option.
+
+The p4 changes will be created as the user invoking 'git p4 submit'. The
+'--preserve-user' option will cause ownership to be modified
+according to the author of the git commit.  This option requires admin
+privileges in p4, which can be granted using 'p4 protect'.
+
+
+OPTIONS
+-------
+
+General options
+~~~~~~~~~~~~~~~
+All commands except clone accept these options.
+
+--git-dir <dir>::
+	Set the 'GIT_DIR' environment variable.  See linkgit:git[1].
+
+--verbose::
+	Provide more progress information.
+
+Sync options
+~~~~~~~~~~~~
+These options can be used in the initial 'clone' as well as in
+subsequent 'sync' operations.
+
+--branch <branch>::
+	Import changes into given branch.  If the branch starts with
+	'refs/', it will be used as is, otherwise the path 'refs/heads/'
+	will be prepended.  The default branch is 'master'.  If used
+	with an initial clone, no HEAD will be checked out.
++
+This example imports a new remote "p4/proj2" into an existing
+git repository:
++
+----
+    $ git init
+    $ git p4 sync --branch=refs/remotes/p4/proj2 //depot/proj2
+----
+
+--detect-branches::
+	Use the branch detection algorithm to find new paths in p4.  It is
+	documented below in "BRANCH DETECTION".
+
+--changesfile <file>::
+	Import exactly the p4 change numbers listed in 'file', one per
+	line.  Normally, 'git p4' inspects the current p4 repository
+	state and detects the changes it should import.
+
+--silent::
+	Do not print any progress information.
+
+--detect-labels::
+	Query p4 for labels associated with the depot paths, and add
+	them as tags in git. Limited usefulness as only imports labels
+	associated with new changelists. Deprecated.
+
+--import-labels::
+	Import labels from p4 into git.
+
+--import-local::
+	By default, p4 branches are stored in 'refs/remotes/p4/',
+	where they will be treated as remote-tracking branches by
+	linkgit:git-branch[1] and other commands.  This option instead
+	puts p4 branches in 'refs/heads/p4/'.  Note that future
+	sync operations must specify '--import-local' as well so that
+	they can find the p4 branches in refs/heads.
+
+--max-changes <n>::
+	Limit the number of imported changes to 'n'.  Useful to
+	limit the amount of history when using the '@all' p4 revision
+	specifier.
+
+--keep-path::
+	The mapping of file names from the p4 depot path to git, by
+	default, involves removing the entire depot path.  With this
+	option, the full p4 depot path is retained in git.  For example,
+	path '//depot/main/foo/bar.c', when imported from
+	'//depot/main/', becomes 'foo/bar.c'.  With '--keep-path', the
+	git path is instead 'depot/main/foo/bar.c'.
+
+--use-client-spec::
+	Use a client spec to find the list of interesting files in p4.
+	See the "CLIENT SPEC" section below.
+
+Clone options
+~~~~~~~~~~~~~
+These options can be used in an initial 'clone', along with the 'sync'
+options described above.
+
+--destination <directory>::
+	Where to create the git repository.  If not provided, the last
+	component in the p4 depot path is used to create a new
+	directory.
+
+--bare::
+	Perform a bare clone.  See linkgit:git-clone[1].
+
+-/ <path>::
+	Exclude selected depot paths when cloning.
+
+Submit options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 submit' behavior.
+
+--origin <commit>::
+	Upstream location from which commits are identified to submit to
+	p4.  By default, this is the most recent p4 commit reachable
+	from 'HEAD'.
+
+-M[<n>]::
+	Detect renames.  See linkgit:git-diff[1].  Renames will be
+	represented in p4 using explicit 'move' operations.  There
+	is no corresponding option to detect copies, but there are
+	variables for both moves and copies.
+
+--preserve-user::
+	Re-author p4 changes before submitting to p4.  This option
+	requires p4 admin privileges.
+
+--export-labels::
+	Export tags from git as p4 labels. Tags found in git are applied
+	to the perforce working directory.
+
+Rebase options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 rebase' behavior.
+
+--import-labels::
+	Import p4 labels.
+
+DEPOT PATH SYNTAX
+-----------------
+The p4 depot path argument to 'git p4 sync' and 'git p4 clone' can
+be one or more space-separated p4 depot paths, with an optional
+p4 revision specifier on the end:
+
+"//depot/my/project"::
+    Import one commit with all files in the '#head' change under that tree.
+
+"//depot/my/project@all"::
+    Import one commit for each change in the history of that depot path.
+
+"//depot/my/project@1,6"::
+    Import only changes 1 through 6.
+
+"//depot/proj1@all //depot/proj2@all"::
+    Import all changes from both named depot paths into a single
+    repository.  Only files below these directories are included.
+    There is not a subdirectory in git for each "proj1" and "proj2".
+    You must use the '--destination' option when specifying more
+    than one depot path.  The revision specifier must be specified
+    identically on each depot path.  If there are files in the
+    depot paths with the same name, the path with the most recently
+    updated version of the file is the one that appears in git.
+
+See 'p4 help revisions' for the full syntax of p4 revision specifiers.
+
+
+CLIENT SPEC
+-----------
+The p4 client specification is maintained with the 'p4 client' command
+and contains among other fields, a View that specifies how the depot
+is mapped into the client repository.  The 'clone' and 'sync' commands
+can consult the client spec when given the '--use-client-spec' option or
+when the useClientSpec variable is true.  After 'git p4 clone', the
+useClientSpec variable is automatically set in the repository
+configuration file.  This allows future 'git p4 submit' commands to
+work properly; the submit command looks only at the variable and does
+not have a command-line option.
+
+The full syntax for a p4 view is documented in 'p4 help views'.  'Git p4'
+knows only a subset of the view syntax.  It understands multi-line
+mappings, overlays with '+', exclusions with '-' and double-quotes
+around whitespace.  Of the possible wildcards, 'git p4' only handles
+'...', and only when it is at the end of the path.  'Git p4' will complain
+if it encounters an unhandled wildcard.
+
+Bugs in the implementation of overlap mappings exist.  If multiple depot
+paths map through overlays to the same location in the repository,
+'git p4' can choose the wrong one.  This is hard to solve without
+dedicating a client spec just for 'git p4'.
+
+The name of the client can be given to 'git p4' in multiple ways.  The
+variable 'git-p4.client' takes precedence if it exists.  Otherwise,
+normal p4 mechanisms of determining the client are used:  environment
+variable P4CLIENT, a file referenced by P4CONFIG, or the local host name.
+
+
+BRANCH DETECTION
+----------------
+P4 does not have the same concept of a branch as git.  Instead,
+p4 organizes its content as a directory tree, where by convention
+different logical branches are in different locations in the tree.
+The 'p4 branch' command is used to maintain mappings between
+different areas in the tree, and indicate related content.  'git p4'
+can use these mappings to determine branch relationships.
+
+If you have a repository where all the branches of interest exist as
+subdirectories of a single depot path, you can use '--detect-branches'
+when cloning or syncing to have 'git p4' automatically find
+subdirectories in p4, and to generate these as branches in git.
+
+For example, if the P4 repository structure is:
+----
+//depot/main/...
+//depot/branch1/...
+----
+
+And "p4 branch -o branch1" shows a View line that looks like:
+----
+//depot/main/... //depot/branch1/...
+----
+
+Then this 'git p4 clone' command:
+----
+git p4 clone --detect-branches //depot@all
+----
+produces a separate branch in 'refs/remotes/p4/' for //depot/main,
+called 'master', and one for //depot/branch1 called 'depot/branch1'.
+
+However, it is not necessary to create branches in p4 to be able to use
+them like branches.  Because it is difficult to infer branch
+relationships automatically, a git configuration setting
+'git-p4.branchList' can be used to explicitly identify branch
+relationships.  It is a list of "source:destination" pairs, like a
+simple p4 branch specification, where the "source" and "destination" are
+the path elements in the p4 repository.  The example above relied on the
+presence of the p4 branch.  Without p4 branches, the same result will
+occur with:
+----
+git config git-p4.branchList main:branch1
+git p4 clone --detect-branches //depot@all
+----
+
+
+PERFORMANCE
+-----------
+The fast-import mechanism used by 'git p4' creates one pack file for
+each invocation of 'git p4 sync'.  Normally, git garbage compression
+(linkgit:git-gc[1]) automatically compresses these to fewer pack files,
+but explicit invocation of 'git repack -adf' may improve performance.
+
+
+CONFIGURATION VARIABLES
+-----------------------
+The following config settings can be used to modify 'git p4' behavior.
+They all are in the 'git-p4' section.
+
+General variables
+~~~~~~~~~~~~~~~~~
+git-p4.user::
+	User specified as an option to all p4 commands, with '-u <user>'.
+	The environment variable 'P4USER' can be used instead.
+
+git-p4.password::
+	Password specified as an option to all p4 commands, with
+	'-P <password>'.
+	The environment variable 'P4PASS' can be used instead.
+
+git-p4.port::
+	Port specified as an option to all p4 commands, with
+	'-p <port>'.
+	The environment variable 'P4PORT' can be used instead.
+
+git-p4.host::
+	Host specified as an option to all p4 commands, with
+	'-h <host>'.
+	The environment variable 'P4HOST' can be used instead.
+
+git-p4.client::
+	Client specified as an option to all p4 commands, with
+	'-c <client>', including the client spec.
+
+Clone and sync variables
+~~~~~~~~~~~~~~~~~~~~~~~~
+git-p4.syncFromOrigin::
+	Because importing commits from other git repositories is much faster
+	than importing them from p4, a mechanism exists to find p4 changes
+	first in git remotes.  If branches exist under 'refs/remote/origin/p4',
+	those will be fetched and used when syncing from p4.  This
+	variable can be set to 'false' to disable this behavior.
+
+git-p4.branchUser::
+	One phase in branch detection involves looking at p4 branches
+	to find new ones to import.  By default, all branches are
+	inspected.  This option limits the search to just those owned
+	by the single user named in the variable.
+
+git-p4.branchList::
+	List of branches to be imported when branch detection is
+	enabled.  Each entry should be a pair of branch names separated
+	by a colon (:).  This example declares that both branchA and
+	branchB were created from main:
++
+-------------
+git config       git-p4.branchList main:branchA
+git config --add git-p4.branchList main:branchB
+-------------
+
+git-p4.ignoredP4Labels::
+	List of p4 labels to ignore. This is built automatically as
+	unimportable labels are discovered.
+
+git-p4.importLabels::
+	Import p4 labels into git, as per --import-labels.
+
+git-p4.labelImportRegexp::
+	Only p4 labels matching this regular expression will be imported. The
+	default value is '[a-zA-Z0-9_\-.]+$'.
+
+git-p4.useClientSpec::
+	Specify that the p4 client spec should be used to identify p4
+	depot paths of interest.  This is equivalent to specifying the
+	option '--use-client-spec'.  See the "CLIENT SPEC" section above.
+	This variable is a boolean, not the name of a p4 client.
+
+Submit variables
+~~~~~~~~~~~~~~~~
+git-p4.detectRenames::
+	Detect renames.  See linkgit:git-diff[1].
+
+git-p4.detectCopies::
+	Detect copies.  See linkgit:git-diff[1].
+
+git-p4.detectCopiesHarder::
+	Detect copies harder.  See linkgit:git-diff[1].
+
+git-p4.preserveUser::
+	On submit, re-author changes to reflect the git author,
+	regardless of who invokes 'git p4 submit'.
+
+git-p4.allowMissingP4Users::
+	When 'preserveUser' is true, 'git p4' normally dies if it
+	cannot find an author in the p4 user map.  This setting
+	submits the change regardless.
+
+git-p4.skipSubmitEdit::
+	The submit process invokes the editor before each p4 change
+	is submitted.  If this setting is true, though, the editing
+	step is skipped.
+
+git-p4.skipSubmitEditCheck::
+	After editing the p4 change message, 'git p4' makes sure that
+	the description really was changed by looking at the file
+	modification time.  This option disables that test.
+
+git-p4.allowSubmit::
+	By default, any branch can be used as the source for a 'git p4
+	submit' operation.  This configuration variable, if set, permits only
+	the named branches to be used as submit sources.  Branch names
+	must be the short names (no "refs/heads/"), and should be
+	separated by commas (","), with no spaces.
+
+git-p4.skipUserNameCheck::
+	If the user running 'git p4 submit' does not exist in the p4
+	user map, 'git p4' exits.  This option can be used to force
+	submission regardless.
+
+git-p4.attemptRCSCleanup::
+	If enabled, 'git p4 submit' will attempt to cleanup RCS keywords
+	($Header$, etc). These would otherwise cause merge conflicts and prevent
+	the submit going ahead. This option should be considered experimental at
+	present.
+
+git-p4.exportLabels::
+	Export git tags to p4 labels, as per --export-labels.
+
+git-p4.labelExportRegexp::
+	Only p4 labels matching this regular expression will be exported. The
+	default value is '[a-zA-Z0-9_\-.]+$'.
+
+IMPLEMENTATION DETAILS
+----------------------
+* Changesets from p4 are imported using git fast-import.
+* Cloning or syncing does not require a p4 client; file contents are
+  collected using 'p4 print'.
+* Submitting requires a p4 client, which is not in the same location
+  as the git repository.  Patches are applied, one at a time, to
+  this p4 client and submitted from there.
+* Each commit imported by 'git p4' has a line at the end of the log
+  message indicating the p4 depot location and change number.  This
+  line is used by later 'git p4 sync' operations to know which p4
+  changes are new.

+=================
+
+NAME
+----
+gitcredentials - providing usernames and passwords to git
+
+SYNOPSIS
+--------
+------------------
+git config credential.https://example.com.username myusername
+git config credential.helper "$helper $options"
+------------------
+
+DESCRIPTION
+-----------
+
+Git will sometimes need credentials from the user in order to perform
+operations; for example, it may need to ask for a username and password
+in order to access a remote repository over HTTP. This manual describes
+the mechanisms git uses to request these credentials, as well as some
+features to avoid inputting these credentials repeatedly.
+
+REQUESTING CREDENTIALS
+----------------------
+
+Without any credential helpers defined, git will try the following
+strategies to ask the user for usernames and passwords:
+
+1. If the `GIT_ASKPASS` environment variable is set, the program
+   specified by the variable is invoked. A suitable prompt is provided
+   to the program on the command line, and the user's input is read
+   from its standard output.
+
+2. Otherwise, if the `core.askpass` configuration variable is set, its
+   value is used as above.
+
+3. Otherwise, if the `SSH_ASKPASS` environment variable is set, its
+   value is used as above.
+
+4. Otherwise, the user is prompted on the terminal.
+
+AVOIDING REPETITION
+-------------------
+
+It can be cumbersome to input the same credentials over and over.  Git
+provides two methods to reduce this annoyance:
+
+1. Static configuration of usernames for a given authentication context.
+
+2. Credential helpers to cache or store passwords, or to interact with
+   a system password wallet or keychain.
+
+The first is simple and appropriate if you do not have secure storage available
+for a password. It is generally configured by adding this to your config:
+
+---------------------------------------
+[credential "https://example.com"]
+	username = me
+---------------------------------------
+
+Credential helpers, on the other hand, are external programs from which git can
+request both usernames and passwords; they typically interface with secure
+storage provided by the OS or other programs.
+
+To use a helper, you must first select one to use. Git currently
+includes the following helpers:
+
+cache::
+
+	Cache credentials in memory for a short period of time. See
+	linkgit:git-credential-cache[1] for details.
+
+store::
+
+	Store credentials indefinitely on disk. See
+	linkgit:git-credential-store[1] for details.
+
+You may also have third-party helpers installed; search for
+`credential-*` in the output of `git help -a`, and consult the
+documentation of individual helpers.  Once you have selected a helper,
+you can tell git to use it by putting its name into the
+credential.helper variable.
+
+1. Find a helper.
++
+-------------------------------------------
+$ git help -a | grep credential-
+credential-foo
+-------------------------------------------
+
+2. Read its description.
++
+-------------------------------------------
+$ git help credential-foo
+-------------------------------------------
+
+3. Tell git to use it.
++
+-------------------------------------------
+$ git config --global credential.helper foo
+-------------------------------------------
+
+If there are multiple instances of the `credential.helper` configuration
+variable, each helper will be tried in turn, and may provide a username,
+password, or nothing. Once git has acquired both a username and a
+password, no more helpers will be tried.
+
+
+CREDENTIAL CONTEXTS
+-------------------
+
+Git considers each credential to have a context defined by a URL. This context
+is used to look up context-specific configuration, and is passed to any
+helpers, which may use it as an index into secure storage.
+
+For instance, imagine we are accessing `https://example.com/foo.git`. When git
+looks into a config file to see if a section matches this context, it will
+consider the two a match if the context is a more-specific subset of the
+pattern in the config file. For example, if you have this in your config file:
+
+--------------------------------------
+[credential "https://example.com"]
+	username = foo
+--------------------------------------
+
+then we will match: both protocols are the same, both hosts are the same, and
+the "pattern" URL does not care about the path component at all. However, this
+context would not match:
+
+--------------------------------------
+[credential "https://kernel.org"]
+	username = foo
+--------------------------------------
+
+because the hostnames differ. Nor would it match `foo.example.com`; git
+compares hostnames exactly, without considering whether two hosts are part of
+the same domain. Likewise, a config entry for `http://example.com` would not
+match: git compares the protocols exactly.
+
+
+CONFIGURATION OPTIONS
+---------------------
+
+Options for a credential context can be configured either in
+`credential.*` (which applies to all credentials), or
+`credential.<url>.*`, where <url> matches the context as described
+above.
+
+The following options are available in either location:
+
+helper::
+
+	The name of an external credential helper, and any associated options.
+	If the helper name is not an absolute path, then the string `git
+	credential-` is prepended. The resulting string is executed by the
+	shell (so, for example, setting this to `foo --option=bar` will execute
+	`git credential-foo --option=bar` via the shell. See the manual of
+	specific helpers for examples of their use.
+
+username::
+
+	A default username, if one is not provided in the URL.
+
+useHttpPath::
+
+	By default, git does not consider the "path" component of an http URL
+	to be worth matching via external helpers. This means that a credential
+	stored for `https://example.com/foo.git` will also be used for
+	`https://example.com/bar.git`. If you do want to distinguish these
+	cases, set this option to `true`.
+
+
+CUSTOM HELPERS
+--------------
+
+You can write your own custom helpers to interface with any system in
+which you keep credentials. See the documentation for git's
+link:technical/api-credentials.html[credentials API] for details.

+NAME
+----
+gitweb.conf - Gitweb (git web interface) configuration file
+
+SYNOPSIS
+--------
+/etc/gitweb.conf, /etc/gitweb-common.conf, $GITWEBDIR/gitweb_config.perl
+
+DESCRIPTION
+-----------
+
+The gitweb CGI script for viewing Git repositories over the web uses a
+perl script fragment as its configuration file.  You can set variables
+using "`our $variable = value`"; text from a "#" character until the
+end of a line is ignored.  See *perlsyn*(1) for details.
+
+An example:
+
+    # gitweb configuration file for http://git.example.org
+    #
+    our $projectroot = "/srv/git"; # FHS recommendation
+    our $site_name = 'Example.org >> Repos';
+
+
+The configuration file is used to override the default settings that
+were built into gitweb at the time the 'gitweb.cgi' script was generated.
+
+While one could just alter the configuration settings in the gitweb
+CGI itself, those changes would be lost upon upgrade.  Configuration
+settings might also be placed into a file in the same directory as the
+CGI script with the default name 'gitweb_config.perl' -- allowing
+one to have multiple gitweb instances with different configurations by
+the use of symlinks.
+
+Note that some configuration can be controlled on per-repository rather than
+gitweb-wide basis: see "Per-repository gitweb configuration" subsection on
+linkgit:gitweb[1] manpage.
+
+
+DISCUSSION
+----------
+Gitweb reads configuration data from the following sources in the
+following order:
+
+ * built-in values (some set during build stage),
+
+ * common system-wide configuration file (defaults to
+   '/etc/gitweb-common.conf'),
+
+ * either per-instance configuration file (defaults to 'gitweb_config.perl'
+   in the same directory as the installed gitweb), or if it does not exists
+   then fallback system-wide configuration file (defaults to '/etc/gitweb.conf').
+
+Values obtained in later configuration files override values obtained earlier
+in the above sequence.
+
+Locations of the common system-wide configuration file, the fallback
+system-wide configuration file and the per-instance configuration file
+are defined at compile time using build-time Makefile configuration
+variables, respectively `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM`
+and `GITWEB_CONFIG`.
+
+You can also override locations of gitweb configuration files during
+runtime by setting the following environment variables:
+`GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` and `GITWEB_CONFIG`
+to a non-empty value.
+
+
+The syntax of the configuration files is that of Perl, since these files are
+handled by sourcing them as fragments of Perl code (the language that
+gitweb itself is written in). Variables are typically set using the
+`our` qualifier (as in "`our $variable = <value>;`") to avoid syntax
+errors if a new version of gitweb no longer uses a variable and therefore
+stops declaring it.
+
+You can include other configuration file using read_config_file()
+subroutine.  For example, one might want to put gitweb configuration
+related to access control for viewing repositories via Gitolite (one
+of git repository management tools) in a separate file, e.g. in
+'/etc/gitweb-gitolite.conf'.  To include it, put
+
+--------------------------------------------------
+read_config_file("/etc/gitweb-gitolite.conf");
+--------------------------------------------------
+
+somewhere in gitweb configuration file used, e.g. in per-installation
+gitweb configuration file.  Note that read_config_file() checks itself
+that the file it reads exists, and does nothing if it is not found.
+It also handles errors in included file.
+
+
+The default configuration with no configuration file at all may work
+perfectly well for some installations.  Still, a configuration file is
+useful for customizing or tweaking the behavior of gitweb in many ways, and
+some optional features will not be present unless explicitly enabled using
+the configurable `%features` variable (see also "Configuring gitweb
+features" section below).
+
+
+CONFIGURATION VARIABLES
+-----------------------
+Some configuration variables have their default values (embedded in the CGI
+script) set during building gitweb -- if that is the case, this fact is put
+in their description.  See gitweb's 'INSTALL' file for instructions on building
+and installing gitweb.
+
+
+Location of repositories
+~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration variables described below control how gitweb finds
+git repositories, and how repositories are displayed and accessed.
+
+See also "Repositories" and later subsections in linkgit:gitweb[1] manpage.
+
+$projectroot::
+	Absolute filesystem path which will be prepended to project path;
+	the path to repository is `$projectroot/$project`.  Set to
+	`$GITWEB_PROJECTROOT` during installation.  This variable has to be
+	set correctly for gitweb to find repositories.
++
+For example, if `$projectroot` is set to "/srv/git" by putting the following
+in gitweb config file:
++
+----------------------------------------------------------------------------
+our $projectroot = "/srv/git";
+----------------------------------------------------------------------------
++
+then
++
+------------------------------------------------
+http://git.example.com/gitweb.cgi?p=foo/bar.git
+------------------------------------------------
++
+and its path_info based equivalent
++
+------------------------------------------------
+http://git.example.com/gitweb.cgi/foo/bar.git
+------------------------------------------------
++
+will map to the path '/srv/git/foo/bar.git' on the filesystem.
+
+$projects_list::
+	Name of a plain text file listing projects, or a name of directory
+	to be scanned for projects.
++
+Project list files should list one project per line, with each line
+having the following format
++
+-----------------------------------------------------------------------------
+<URI-encoded filesystem path to repository> SP <URI-encoded repository owner>
+-----------------------------------------------------------------------------
++
+The default value of this variable is determined by the `GITWEB_LIST`
+makefile variable at installation time.  If this variable is empty, gitweb
+will fall back to scanning the `$projectroot` directory for repositories.
+
+$project_maxdepth::
+	If `$projects_list` variable is unset, gitweb will recursively
+	scan filesystem for git repositories.  The `$project_maxdepth`
+	is used to limit traversing depth, relative to `$projectroot`
+	(starting point); it means that directories which are further
+	from `$projectroot` than `$project_maxdepth` will be skipped.
++
+It is purely performance optimization, originally intended for MacOS X,
+where recursive directory traversal is slow.  Gitweb follows symbolic
+links, but it detects cycles, ignoring any duplicate files and directories.
++
+The default value of this variable is determined by the build-time
+configuration variable `GITWEB_PROJECT_MAXDEPTH`, which defaults to
+2007.
+
+$export_ok::
+	Show repository only if this file exists (in repository).  Only
+	effective if this variable evaluates to true.  Can be set when
+	building gitweb by setting `GITWEB_EXPORT_OK`.  This path is
+	relative to `GIT_DIR`.  git-daemon[1] uses 'git-daemon-export-ok',
+	unless started with `--export-all`.  By default this variable is
+	not set, which means that this feature is turned off.
+
+$export_auth_hook::
+	Function used to determine which repositories should be shown.
+	This subroutine should take one parameter, the full path to
+	a project, and if it returns true, that project will be included
+	in the projects list and can be accessed through gitweb as long
+	as it fulfills the other requirements described by $export_ok,
+	$projects_list, and $projects_maxdepth.  Example:
++
+----------------------------------------------------------------------------
+our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; };
+----------------------------------------------------------------------------
++
+though the above might be done by using `$export_ok` instead
++
+----------------------------------------------------------------------------
+our $export_ok = "git-daemon-export-ok";
+----------------------------------------------------------------------------
++
+If not set (default), it means that this feature is disabled.
++
+See also more involved example in "Controlling access to git repositories"
+subsection on linkgit:gitweb[1] manpage.
+
+$strict_export::
+	Only allow viewing of repositories also shown on the overview page.
+	This for example makes `$gitweb_export_ok` file decide if repository is
+	available and not only if it is shown.  If `$gitweb_list` points to
+	file with list of project, only those repositories listed would be
+	available for gitweb.  Can be set during building gitweb via
+	`GITWEB_STRICT_EXPORT`.  By default this variable is not set, which
+	means that you can directly access those repositories that are hidden
+	from projects list page (e.g. the are not listed in the $projects_list
+	file).
+
+
+Finding files
+~~~~~~~~~~~~~
+The following configuration variables tell gitweb where to find files.
+The values of these variables are paths on the filesystem.
+
+$GIT::
+	Core git executable to use.  By default set to `$GIT_BINDIR/git`, which
+	in turn is by default set to `$(bindir)/git`.  If you use git installed
+	from a binary package, you should usually set this to "/usr/bin/git".
+	This can just be "git" if your web server has a sensible PATH; from
+	security point of view it is better to use absolute path to git binary.
+	If you have multiple git versions installed it can be used to choose
+	which one to use.  Must be (correctly) set for gitweb to be able to
+	work.
+
+$mimetypes_file::
+	File to use for (filename extension based) guessing of MIME types before
+	trying '/etc/mime.types'.  *NOTE* that this path, if relative, is taken
+	as relative to the current git repository, not to CGI script.  If unset,
+	only '/etc/mime.types' is used (if present on filesystem).  If no mimetypes
+	file is found, mimetype guessing based on extension of file is disabled.
+	Unset by default.
+
+$highlight_bin::
+	Path to the highlight executable to use (it must be the one from
+	http://www.andre-simon.de[] due to assumptions about parameters and output).
+	By default set to 'highlight'; set it to full path to highlight
+	executable if it is not installed on your web server's PATH.
+	Note that 'highlight' feature must be set for gitweb to actually
+	use syntax highlighting.
++
+*NOTE*: if you want to add support for new file type (supported by
+"highlight" but not used by gitweb), you need to modify `%highlight_ext`
+or `%highlight_basename`, depending on whether you detect type of file
+based on extension (for example "sh") or on its basename (for example
+"Makefile").  The keys of these hashes are extension and basename,
+respectively, and value for given key is name of syntax to be passed via
+`--syntax <syntax>` to highlighter.
++
+For example if repositories you are hosting use "phtml" extension for
+PHP files, and you want to have correct syntax-highlighting for those
+files, you can add the following to gitweb configuration:
++
+---------------------------------------------------------
+our %highlight_ext;
+$highlight_ext{'phtml'} = 'php';
+---------------------------------------------------------
+
+
+Links and their targets
+~~~~~~~~~~~~~~~~~~~~~~~
+The configuration variables described below configure some of gitweb links:
+their target and their look (text or image), and where to find page
+prerequisites (stylesheet, favicon, images, scripts).  Usually they are left
+at their default values, with the possible exception of `@stylesheets`
+variable.
+
+@stylesheets::
+	List of URIs of stylesheets (relative to the base URI of a page). You
+	might specify more than one stylesheet, for example to use "gitweb.css"
+	as base with site specific modifications in a separate stylesheet
+	to make it easier to upgrade gitweb.  For example, you can add
+	a `site` stylesheet by putting
++
+----------------------------------------------------------------------------
+push @stylesheets, "gitweb-site.css";
+----------------------------------------------------------------------------
++
+in the gitweb config file.  Those values that are relative paths are
+relative to base URI of gitweb.
++
+This list should contain the URI of gitweb's standard stylesheet.  The default
+URI of gitweb stylesheet can be set at build time using the `GITWEB_CSS`
+makefile variable.  Its default value is 'static/gitweb.css'
+(or 'static/gitweb.min.css' if the `CSSMIN` variable is defined,
+i.e. if CSS minifier is used during build).
++
+*Note*: there is also a legacy `$stylesheet` configuration variable, which was
+used by older gitweb.  If `$stylesheet` variable is defined, only CSS stylesheet
+given by this variable is used by gitweb.
+
+$logo::
+	Points to the location where you put 'git-logo.png' on your web
+	server, or to be more the generic URI of logo, 72x27 size).  This image
+	is displayed in the top right corner of each gitweb page and used as
+	a logo for the Atom feed.  Relative to the base URI of gitweb (as a path).
+	Can be adjusted when building gitweb using `GITWEB_LOGO` variable
+	By default set to 'static/git-logo.png'.
+
+$favicon::
+	Points to the location where you put 'git-favicon.png' on your web
+	server, or to be more the generic URI of favicon, which will be served
+	as "image/png" type.  Web browsers that support favicons (website icons)
+	may display them in the browser's URL bar and next to the site name in
+	bookmarks.  Relative to the base URI of gitweb.  Can be adjusted at
+	build time using `GITWEB_FAVICON` variable.
+	By default set to 'static/git-favicon.png'.
+
+$javascript::
+	Points to the location where you put 'gitweb.js' on your web server,
+	or to be more generic the URI of JavaScript code used by gitweb.
+	Relative to the base URI of gitweb.  Can be set at build time using
+	the `GITWEB_JS` build-time configuration variable.
++
+The default value is either 'static/gitweb.js', or 'static/gitweb.min.js' if
+the `JSMIN` build variable was defined, i.e. if JavaScript minifier was used
+at build time.  *Note* that this single file is generated from multiple
+individual JavaScript "modules".
+
+$home_link::
+	Target of the home link on the top of all pages (the first part of view
+	"breadcrumbs").  By default it is set to the absolute URI of a current page
+	(to the value of `$my_uri` variable, or to "/" if `$my_uri` is undefined
+	or is an empty string).
+
+$home_link_str::
+	Label for the "home link" at the top of all pages, leading to `$home_link`
+	(usually the main gitweb page, which contains the projects list).  It is
+	used as the first component of gitweb's "breadcrumb trail":
+	`<home link> / <project> / <action>`.  Can be set at build time using
+	the `GITWEB_HOME_LINK_STR` variable.  By default it is set to "projects",
+	as this link leads to the list of projects.  Other popular choice it to
+	set it to the name of site.
+
+$logo_url::
+$logo_label::
+	URI and label (title) for the Git logo link (or your site logo,
+	if you chose to use different logo image). By default, these both
+	refer to git homepage, http://git-scm.com[]; in the past, they pointed
+	to git documentation at http://www.kernel.org[].
+
+
+Changing gitweb's look
+~~~~~~~~~~~~~~~~~~~~~~
+You can adjust how pages generated by gitweb look using the variables described
+below.  You can change the site name, add common headers and footers for all
+pages, and add a description of this gitweb installation on its main page
+(which is the projects list page), etc.
+
+$site_name::
+	Name of your site or organization, to appear in page titles.  Set it
+	to something descriptive for clearer bookmarks etc.  If this variable
+	is not set or is, then gitweb uses the value of the `SERVER_NAME`
+	CGI environment variable, setting site name to "$SERVER_NAME Git",
+	or "Untitled Git" if this variable is not set (e.g. if running gitweb
+	as standalone script).
++
+Can be set using the `GITWEB_SITENAME` at build time.  Unset by default.
+
+$site_html_head_string::
+	HTML snippet to be included in the <head> section of each page.
+	Can be set using `GITWEB_SITE_HTML_HEAD_STRING` at build time.
+	No default value.
+
+$site_header::
+	Name of a file with HTML to be included at the top of each page.
+	Relative to the directory containing the 'gitweb.cgi' script.
+	Can be set using `GITWEB_SITE_HEADER` at build time.  No default
+	value.
+
+$site_footer::
+	Name of a file with HTML to be included at the bottom of each page.
+	Relative to the directory containing the 'gitweb.cgi' script.
+	Can be set using `GITWEB_SITE_FOOTER` at build time.  No default
+	value.
+
+$home_text::
+	Name of a HTML file which, if it exists, is included on the
+	gitweb projects overview page ("projects_list" view).  Relative to
+	the directory containing the gitweb.cgi script.  Default value
+	can be adjusted during build time using `GITWEB_HOMETEXT` variable.
+	By default set to 'indextext.html'.
+
+$projects_list_description_width::
+	The width (in characters) of the "Description" column of the projects list.
+	Longer descriptions will be truncated (trying to cut at word boundary);
+	the full description is available in the 'title' attribute (usually shown on
+	mouseover).  The default is 25, which might be too small if you
+	use long project descriptions.
+
+$default_projects_order::
+	Default value of ordering of projects on projects list page, which
+	means the ordering used if you don't explicitly sort projects list
+	(if there is no "o" CGI query parameter in the URL).  Valid values
+	are "none" (unsorted), "project" (projects are by project name,
+	i.e. path to repository relative to `$projectroot`), "descr"
+	(project description), "owner", and "age" (by date of most current
+	commit).
++
+Default value is "project".  Unknown value means unsorted.
+
+
+Changing gitweb's behavior
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+These configuration variables control _internal_ gitweb behavior.
+
+$default_blob_plain_mimetype::
+	Default mimetype for the blob_plain (raw) view, if mimetype checking
+	doesn't result in some other type; by default "text/plain".
+	Gitweb guesses mimetype of a file to display based on extension
+	of its filename, using `$mimetypes_file` (if set and file exists)
+	and '/etc/mime.types' files (see *mime.types*(5) manpage; only
+	filename extension rules are supported by gitweb).
+
+$default_text_plain_charset::
+	Default charset for text files. If this is not set, the web server
+	configuration will be used.  Unset by default.
+
+$fallback_encoding::
+	Gitweb assumes this charset when a line contains non-UTF-8 characters.
+	The fallback decoding is used without error checking, so it can be even
+	"utf-8". The value must be a valid encoding; see the *Encoding::Supported*(3pm)
+	man page for a list. The default is "latin1", aka. "iso-8859-1".
+
+@diff_opts::
+	Rename detection options for git-diff and git-diff-tree. The default is
+	(\'-M'); set it to (\'-C') or (\'-C', \'-C') to also detect copies,
+	or set it to () i.e. empty list if you don't want to have renames
+	detection.
++
+*Note* that rename and especially copy detection can be quite
+CPU-intensive.  Note also that non git tools can have problems with
+patches generated with options mentioned above, especially when they
+involve file copies (\'-C') or criss-cross renames (\'-B').
+
+
+Some optional features and policies
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Most of features are configured via `%feature` hash; however some of extra
+gitweb features can be turned on and configured using variables described
+below.  This list beside configuration variables that control how gitweb
+looks does contain variables configuring administrative side of gitweb
+(e.g. cross-site scripting prevention; admittedly this as side effect
+affects how "summary" pages look like, or load limiting).
+
+@git_base_url_list::
+	List of git base URLs.  These URLs are used to generate URLs
+	describing from where to fetch a project, which are shown on
+	project summary page.  The full fetch URL is "`$git_base_url/$project`",
+	for each element of this list. You can set up multiple base URLs
+	(for example one for `git://` protocol, and one for `http://`
+	protocol).
++
+Note that per repository configuration can be set in '$GIT_DIR/cloneurl'
+file, or as values of multi-value `gitweb.url` configuration variable in
+project config.  Per-repository configuration takes precedence over value
+composed from `@git_base_url_list` elements and project name.
++
+You can setup one single value (single entry/item in this list) at build
+time by setting the `GITWEB_BASE_URL` built-time configuration variable.
+By default it is set to (), i.e. an empty list.  This means that gitweb
+would not try to create project URL (to fetch) from project name.
+
+$projects_list_group_categories::
+	Whether to enables the grouping of projects by category on the project
+	list page. The category of a project is determined by the
+	`$GIT_DIR/category` file or the `gitweb.category` variable in each
+	repository's configuration.  Disabled by default (set to 0).
+
+$project_list_default_category::
+	Default category for projects for which none is specified.  If this is
+	set to the empty string, such projects will remain uncategorized and
+	listed at the top, above categorized projects.  Used only if project
+	categories are enabled, which means if `$projects_list_group_categories`
+	is true.  By default set to "" (empty string).
+
+$prevent_xss::
+	If true, some gitweb features are disabled to prevent content in
+	repositories from launching cross-site scripting (XSS) attacks.  Set this
+	to true if you don't trust the content of your repositories.
+	False by default (set to 0).
+
+$maxload::
+	Used to set the maximum load that we will still respond to gitweb queries.
+	If the server load exceeds this value then gitweb will return
+	"503 Service Unavailable" error.  The server load is taken to be 0
+	if gitweb cannot determine its value.  Currently it works only on Linux,
+	where it uses '/proc/loadavg'; the load there is the number of active
+	tasks on the system -- processes that are actually running -- averaged
+	over the last minute.
++
+Set `$maxload` to undefined value (`undef`) to turn this feature off.
+The default value is 300.
+
+$omit_age_column::
+	If true, omit the column with date of the most current commit on the
+	projects list page. It can save a bit of I/O and a fork per repository.
+
+$omit_owner::
+	If true prevents displaying information about repository owner.
+
+$per_request_config::
+	If this is set to code reference, it will be run once for each request.
+	You can	set parts of configuration that change per session this way.
+	For example, one might use the following code in a gitweb configuration
+	file
++
+--------------------------------------------------------------------------------
+our $per_request_config = sub {
+	$ENV{GL_USER} = $cgi->remote_user || "gitweb";
+};
+--------------------------------------------------------------------------------
++
+If `$per_request_config` is not a code reference, it is interpreted as boolean
+value.  If it is true gitweb will process config files once per request,
+and if it is false gitweb will process config files only once, each time it
+is executed.  True by default (set to 1).
++
+*NOTE*: `$my_url`, `$my_uri`, and `$base_url` are overwritten with their default
+values before every request, so if you want to change them, be sure to set
+this variable to true or a code reference effecting the desired changes.
++
+This variable matters only when using persistent web environments that
+serve multiple requests using single gitweb instance, like mod_perl,
+FastCGI or Plackup.
+
+
+Other variables
+~~~~~~~~~~~~~~~
+Usually you should not need to change (adjust) any of configuration
+variables described below; they should be automatically set by gitweb to
+correct value.
+
+
+$version::
+	Gitweb version, set automatically when creating gitweb.cgi from
+	gitweb.perl. You might want to modify it if you are running modified
+	gitweb, for example
++
+---------------------------------------------------
+our $version .= " with caching";
+---------------------------------------------------
++
+if you run modified version of gitweb with caching support.  This variable
+is purely informational, used e.g. in the "generator" meta header in HTML
+header.
+
+$my_url::
+$my_uri::
+	Full URL and absolute URL of the gitweb script;
+	in earlier versions of gitweb you might have need to set those
+	variables, but now there should be no need to do it.  See
+	`$per_request_config` if you need to set them still.
+
+$base_url::
+	Base URL for relative URLs in pages generated by gitweb,
+	(e.g. `$logo`, `$favicon`, `@stylesheets` if they are relative URLs),
+	needed and used '<base href="$base_url">' only for URLs with nonempty
+	PATH_INFO.  Usually gitweb sets its value correctly,
+	and there is no need to set this variable, e.g. to $my_uri or "/".
+	See `$per_request_config` if you need to override it anyway.
+
+
+CONFIGURING GITWEB FEATURES
+---------------------------
+Many gitweb features can be enabled (or disabled) and configured using the
+`%feature` hash.  Names of gitweb features are keys of this hash.
+
+Each `%feature` hash element is a hash reference and has the following
+structure:
+----------------------------------------------------------------------
+"<feature_name>" => {
+	"sub" => <feature-sub (subroutine)>,
+	"override" => <allow-override (boolean)>,
+	"default" => [ <options>... ]
+},
+----------------------------------------------------------------------
+Some features cannot be overridden per project.  For those
+features the structure of appropriate `%feature` hash element has a simpler
+form:
+----------------------------------------------------------------------
+"<feature_name>" => {
+	"override" => 0,
+	"default" => [ <options>... ]
+},
+----------------------------------------------------------------------
+As one can see it lacks the \'sub' element.
+
+The meaning of each part of feature configuration is described
+below:
+
+default::
+	List (array reference) of feature parameters (if there are any),
+	used also to toggle (enable or disable) given feature.
++
+Note that it is currently *always* an array reference, even if
+feature doesn't accept any configuration parameters, and \'default'
+is used only to turn it on or off.  In such case you turn feature on
+by setting this element to `[1]`, and torn it off by setting it to
+`[0]`.  See also the passage about the "blame" feature in the "Examples"
+section.
++
+To disable features that accept parameters (are configurable), you
+need to set this element to empty list i.e. `[]`.
+
+override::
+	If this field has a true value then the given feature is
+	overriddable, which means that it can be configured
+	(or enabled/disabled) on a per-repository basis.
++
+Usually given "<feature>" is configurable via the `gitweb.<feature>`
+config variable in the per-repository git configuration file.
++
+*Note* that no feature is overriddable by default.
+
+sub::
+	Internal detail of implementation.  What is important is that
+	if this field is not present then per-repository override for
+	given feature is not supported.
++
+You wouldn't need to ever change it in gitweb config file.
+
+
+Features in `%feature`
+~~~~~~~~~~~~~~~~~~~~~~
+The gitweb features that are configurable via `%feature` hash are listed
+below.  This should be a complete list, but ultimately the authoritative
+and complete list is in gitweb.cgi source code, with features described
+in the comments.
+
+blame::
+	Enable the "blame" and "blame_incremental" blob views, showing for
+	each line the last commit that modified it; see linkgit:git-blame[1].
+	This can be very CPU-intensive and is therefore disabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.blame` configuration variable (boolean).
+
+snapshot::
+	Enable and configure the "snapshot" action, which allows user to
+	download a compressed archive of any tree or commit, as produced
+	by linkgit:git-archive[1] and possibly additionally compressed.
+	This can potentially generate high traffic if you have large project.
++
+The value of \'default' is a list of names of snapshot formats,
+defined in `%known_snapshot_formats` hash, that you wish to offer.
+Supported formats include "tgz", "tbz2", "txz" (gzip/bzip2/xz
+compressed tar archive) and "zip"; please consult gitweb sources for
+a definitive list.  By default only "tgz" is offered.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.blame` configuration variable, which contains
+a comma separated list of formats or "none" to disable snapshots.
+Unknown values are ignored.
+
+grep::
+	Enable grep search, which lists the files in currently selected
+	tree (directory) containing the given string; see linkgit:git-grep[1].
+	This can be potentially CPU-intensive, of course.  Enabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.grep` configuration variable (boolean).
+
+pickaxe::
+	Enable the so called pickaxe search, which will list the commits
+	that introduced or removed a given string in a file.  This can be
+	practical and quite faster alternative to "blame" action, but it is
+	still potentially CPU-intensive.  Enabled by default.
++
+The pickaxe search is described in linkgit:git-log[1] (the
+description of `-S<string>` option, which refers to pickaxe entry in
+linkgit:gitdiffcore[7] for more details).
++
+This feature can be configured on a per-repository basis by setting
+repository's `gitweb.pickaxe` configuration variable (boolean).
+
+show-sizes::
+	Enable showing size of blobs (ordinary files) in a "tree" view, in a
+	separate column, similar to what `ls -l` does; see description of
+	`-l` option in linkgit:git-ls-tree[1] manpage.  This costs a bit of
+	I/O.  Enabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.showsizes` configuration variable (boolean).
+
+patches::
+	Enable and configure "patches" view, which displays list of commits in email
+	(plain text) output format; see also linkgit:git-format-patch[1].
+	The value is the maximum number of patches in a patchset generated
+	in "patches" view.  Set the 'default' field to a list containing single
+	item of or to an empty list to disable patch view, or to a list
+	containing a single negative number to remove any limit.
+	Default value is 16.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.patches` configuration variable (integer).
+
+avatar::
+	Avatar support.  When this feature is enabled, views such as
+	"shortlog" or "commit" will display an avatar associated with
+	the email of each committer and author.
++
+Currently available providers are *"gravatar"* and *"picon"*.
+Only one provider at a time can be selected ('default' is one element list).
+If an unknown provider is specified, the feature is disabled.
+*Note* that some providers might require extra Perl packages to be
+installed; see 'gitweb/INSTALL' for more details.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.avatar` configuration variable.
++
+See also `%avatar_size` with pixel sizes for icons and avatars
+("default" is used for one-line like "log" and "shortlog", "double"
+is used for two-line like "commit", "commitdiff" or "tag").  If the
+default font sizes or lineheights are changed (e.g. via adding extra
+CSS stylesheet in `@stylesheets`), it may be appropriate to change
+these values.
+
+highlight::
+	Server-side syntax highlight support in "blob" view.  It requires
+	`$highlight_bin` program to be available (see the description of
+	this variable in the "Configuration variables" section above),
+	and therefore is disabled by default.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.highlight` configuration variable (boolean).
+
+remote_heads::
+	Enable displaying remote heads (remote-tracking branches) in the "heads"
+	list.  In most cases the list of remote-tracking branches is an
+	unnecessary internal private detail, and this feature is therefore
+	disabled by default.  linkgit:git-instaweb[1], which is usually used
+	to browse local repositories, enables and uses this feature.
++
+This feature can be configured on a per-repository basis via
+repository's `gitweb.remote_heads` configuration variable (boolean).
+
+
+The remaining features cannot be overridden on a per project basis.
+
+search::
+	Enable text search, which will list the commits which match author,
+	committer or commit text to a given string; see the description of
+	`--author`, `--committer` and `--grep` options in linkgit:git-log[1]
+	manpage.  Enabled by default.
++
+Project specific override is not supported.
+
+forks::
+	If this feature is enabled, gitweb considers projects in
+	subdirectories of project root (basename) to be forks of existing
+	projects.  For each project +$projname.git+, projects in the
+	+$projname/+ directory and its subdirectories will not be
+	shown in the main projects list.  Instead, a \'\+' mark is shown
+	next to +$projname+, which links to a "forks" view that lists all
+	the forks (all projects in +$projname/+ subdirectory).  Additionally
+	a "forks" view for a project is linked from project summary page.
++
+If the project list is taken from a file (+$projects_list+ points to a
+file), forks are only recognized if they are listed after the main project
+in that file.
++
+Project specific override is not supported.
+
+actions::
+	Insert custom links to the action bar of all project pages.  This
+	allows you to link to third-party scripts integrating into gitweb.
++
+The "default" value consists of a list of triplets in the form
+`("<label>", "<link>", "<position>")` where "position" is the label
+after which to insert the link, "link" is a format string where `%n`
+expands to the project name, `%f` to the project path within the
+filesystem (i.e. "$projectroot/$project"), `%h` to the current hash
+(\'h' gitweb parameter) and `%b` to the current hash base
+(\'hb' gitweb parameter); `%%` expands to \'%'.
++
+For example, at the time this page was written, the http://repo.or.cz[]
+git hosting site set it to the following to enable graphical log
+(using the third party tool *git-browser*):
++
+----------------------------------------------------------------------
+$feature{'actions'}{'default'} =
+	[ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')];
+----------------------------------------------------------------------
++
+This adds a link titled "graphiclog" after the "summary" link, leading to
+`git-browser` script, passing `r=<project>` as a query parameter.
++
+Project specific override is not supported.
+
+timed::
+	Enable displaying how much time and how many git commands it took to
+	generate and display each page in the page footer (at the bottom of
+	page).  For example the footer might contain: "This page took 6.53325
+	seconds and 13 git commands to generate."  Disabled by default.
++
+Project specific override is not supported.
+
+javascript-timezone::
+	Enable and configure the ability to change a common timezone for dates
+	in gitweb output via JavaScript.  Dates in gitweb output include
+	authordate and committerdate in "commit", "commitdiff" and "log"
+	views, and taggerdate in "tag" view.  Enabled by default.
++
+The value is a list of three values: a default timezone (for if the client
+hasn't selected some other timezone and saved it in a cookie), a name of cookie
+where to store selected timezone, and a CSS class used to mark up
+dates for manipulation.  If you want to turn this feature off, set "default"
+to empty list: `[]`.
++
+Typical gitweb config files will only change starting (default) timezone,
+and leave other elements at their default values:
++
+---------------------------------------------------------------------------
+$feature{'javascript-timezone'}{'default'}[0] = "utc";
+---------------------------------------------------------------------------
++
+The example configuration presented here is guaranteed to be backwards
+and forward compatible.
++
+Timezone values can be "local" (for local timezone that browser uses), "utc"
+(what gitweb uses when JavaScript or this feature is disabled), or numerical
+timezones in the form of "+/-HHMM", such as "+0200".
++
+Project specific override is not supported.
+
+
+EXAMPLES
+--------
+
+To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and
+"zip" snapshots), while allowing individual projects to turn them off, put
+the following in your GITWEB_CONFIG file:
+
+	$feature{'blame'}{'default'} = [1];
+	$feature{'blame'}{'override'} = 1;
+
+	$feature{'pickaxe'}{'default'} = [1];
+	$feature{'pickaxe'}{'override'} = 1;
+
+	$feature{'snapshot'}{'default'} = ['zip', 'tgz'];
+	$feature{'snapshot'}{'override'} = 1;
+
+If you allow overriding for the snapshot feature, you can specify which
+snapshot formats are globally disabled. You can also add any command line
+options you want (such as setting the compression level). For instance, you
+can disable Zip compressed snapshots and set *gzip*(1) to run at level 6 by
+adding the following lines to your gitweb configuration file:
+
+	$known_snapshot_formats{'zip'}{'disabled'} = 1;
+	$known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6'];
+
+ENVIRONMENT
+-----------
+The location of per-instance and system-wide configuration files can be
+overridden using the following environment variables:
+
+GITWEB_CONFIG::
+	Sets location of per-instance configuration file.
+GITWEB_CONFIG_SYSTEM::
+	Sets location of fallback system-wide configuration file.
+	This file is read only if per-instance one does not exist.
+GITWEB_CONFIG_COMMON::
+	Sets location of common system-wide configuration file.
+
+
+FILES
+-----
+gitweb_config.perl::
+	This is default name of per-instance configuration file.  The
+	format of this file is described above.
+/etc/gitweb.conf::
+	This is default name of fallback system-wide configuration
+	file.  This file is used only if per-instance configuration
+	variable is not found.
+/etc/gitweb-common.conf::
+	This is default name of common system-wide configuration
+	file.

+NAME
+----
+gitweb - Git web interface (web frontend to Git repositories)
+
+SYNOPSIS
+--------
+To get started with gitweb, run linkgit:git-instaweb[1] from a git repository.
+This would configure and start your web server, and run web browser pointing to
+gitweb.
+
+
+DESCRIPTION
+-----------
+Gitweb provides a web interface to git repositories.  Its features include:
+
+* Viewing multiple Git repositories with common root.
+* Browsing every revision of the repository.
+* Viewing the contents of files in the repository at any revision.
+* Viewing the revision log of branches, history of files and directories,
+  see what was changed when, by who.
+* Viewing the blame/annotation details of any file (if enabled).
+* Generating RSS and Atom feeds of commits, for any branch.
+  The feeds are auto-discoverable in modern web browsers.
+* Viewing everything that was changed in a revision, and step through
+  revisions one at a time, viewing the history of the repository.
+* Finding commits which commit messages matches given search term.
+
+See http://git.kernel.org/?p=git/git.git;a=tree;f=gitweb[] or
+http://repo.or.cz/w/git.git/tree/HEAD:/gitweb/[] for gitweb source code,
+browsed using gitweb itself.
+
+
+CONFIGURATION
+-------------
+Various aspects of gitweb's behavior can be controlled through the configuration
+file 'gitweb_config.perl' or '/etc/gitweb.conf'.  See the linkgit:gitweb.conf[5]
+for details.
+
+Repositories
+~~~~~~~~~~~~
+Gitweb can show information from one or more Git repositories.  These
+repositories have to be all on local filesystem, and have to share common
+repository root, i.e. be all under a single parent repository (but see also
+"Advanced web server setup" section, "Webserver configuration with multiple
+projects' root" subsection).
+
+-----------------------------------------------------------------------
+our $projectroot = '/path/to/parent/directory';
+-----------------------------------------------------------------------
+
+The default value for `$projectroot` is '/pub/git'.  You can change it during
+building gitweb via `GITWEB_PROJECTROOT` build configuration variable.
+
+By default all git repositories under `$projectroot` are visible and available
+to gitweb.  The list of projects is generated by default by scanning the
+`$projectroot` directory for git repositories (for object databases to be
+more exact; gitweb is not interested in a working area, and is best suited
+to showing "bare" repositories).
+
+The name of the repository in gitweb is the path to its `$GIT_DIR` (its object
+database) relative to `$projectroot`.  Therefore the repository $repo can be
+found at "$projectroot/$repo".
+
+
+Projects list file format
+~~~~~~~~~~~~~~~~~~~~~~~~~
+Instead of having gitweb find repositories by scanning filesystem
+starting from $projectroot, you can provide a pre-generated list of
+visible projects by setting `$projects_list` to point to a plain text
+file with a list of projects (with some additional info).
+
+This file uses the following format:
+
+* One record (for project / repository) per line; does not support line
+continuation (newline escaping).
+
+* Leading and trailing whitespace are ignored.
+
+* Whitespace separated fields; any run of whitespace can be used as field
+separator (rules for Perl's "`split(" ", $line)`").
+
+* Fields use modified URI encoding, defined in RFC 3986, section 2.1
+(Percent-Encoding), or rather "Query string encoding" (see
+link:http://en.wikipedia.org/wiki/Query_string#URL_encoding[]), the difference
+being that SP (" ") can be encoded as "{plus}" (and therefore "{plus}" has to be
+also percent-encoded).
++
+Reserved characters are: "%" (used for encoding), "{plus}" (can be used to
+encode SPACE), all whitespace characters as defined in Perl, including SP,
+TAB and LF, (used to separate fields in a record).
+
+* Currently recognized fields are:
+<repository path>::
+	path to repository GIT_DIR, relative to `$projectroot`
+<repository owner>::
+	displayed as repository owner, preferably full name, or email,
+	or both
+
+You can generate the projects list index file using the project_index action
+(the 'TXT' link on projects list page) directly from gitweb; see also
+"Generating projects list using gitweb" section below.
+
+Example contents:
+-----------------------------------------------------------------------
+foo.git       Joe+R+Hacker+<joe@example.com>
+foo/bar.git   O+W+Ner+<owner@example.org>
+-----------------------------------------------------------------------
+
+
+By default this file controls only which projects are *visible* on projects
+list page (note that entries that do not point to correctly recognized git
+repositories won't be displayed by gitweb).  Even if a project is not
+visible on projects list page, you can view it nevertheless by hand-crafting
+a gitweb URL.  By setting `$strict_export` configuration variable (see
+linkgit:gitweb.conf[5]) to true value you can allow viewing only of
+repositories also shown on the overview page (i.e. only projects explicitly
+listed in projects list file will be accessible).
+
+
+Generating projects list using gitweb
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We assume that GITWEB_CONFIG has its default Makefile value, namely
+'gitweb_config.perl'. Put the following in 'gitweb_make_index.perl' file:
+----------------------------------------------------------------------------
+read_config_file("gitweb_config.perl");
+$projects_list = $projectroot;
+----------------------------------------------------------------------------
+
+Then create the following script to get list of project in the format
+suitable for GITWEB_LIST build configuration variable (or
+`$projects_list` variable in gitweb config):
+
+----------------------------------------------------------------------------
+#!/bin/sh
+
+export GITWEB_CONFIG="gitweb_make_index.perl"
+export GATEWAY_INTERFACE="CGI/1.1"
+export HTTP_ACCEPT="*/*"
+export REQUEST_METHOD="GET"
+export QUERY_STRING="a=project_index"
+
+perl -- /var/www/cgi-bin/gitweb.cgi
+----------------------------------------------------------------------------
+
+Run this script and save its output to a file.  This file could then be used
+as projects list file, which means that you can set `$projects_list` to its
+filename.
+
+
+Controlling access to git repositories
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+By default all git repositories under `$projectroot` are visible and
+available to gitweb.  You can however configure how gitweb controls access
+to repositories.
+
+* As described in "Projects list file format" section, you can control which
+projects are *visible* by selectively including repositories in projects
+list file, and setting `$projects_list` gitweb configuration variable to
+point to it.  With `$strict_export` set, projects list file can be used to
+control which repositories are *available* as well.
+
+* You can configure gitweb to only list and allow viewing of the explicitly
+exported repositories, via `$export_ok` variable in gitweb config file; see
+linkgit:gitweb.conf[5] manpage.  If it evaluates to true, gitweb shows
+repositories only if this file named by `$export_ok` exists in its object
+database (if directory has the magic file named `$export_ok`).
++
+For example linkgit:git-daemon[1] by default (unless `--export-all` option
+is used) allows pulling only for those repositories that have
+'git-daemon-export-ok' file.  Adding
++
+--------------------------------------------------------------------------
+our $export_ok = "git-daemon-export-ok";
+--------------------------------------------------------------------------
++
+makes gitweb show and allow access only to those repositories that can be
+fetched from via `git://` protocol.
+
+* Finally, it is possible to specify an arbitrary perl subroutine that will
+be called for each repository to determine if it can be exported.  The
+subroutine receives an absolute path to the project (repository) as its only
+parameter (i.e. "$projectroot/$project").
++
+For example, if you use mod_perl to run the script, and have dumb
+HTTP protocol authentication configured for your repositories, you
+can use the following hook to allow access only if the user is
+authorized to read the files:
++
+--------------------------------------------------------------------------
+$export_auth_hook = sub {
+	use Apache2::SubRequest ();
+	use Apache2::Const -compile => qw(HTTP_OK);
+	my $path = "$_[0]/HEAD";
+	my $r    = Apache2::RequestUtil->request;
+	my $sub  = $r->lookup_file($path);
+	return $sub->filename eq $path
+	    && $sub->status == Apache2::Const::HTTP_OK;
+};
+--------------------------------------------------------------------------
+
+
+Per-repository gitweb configuration
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can configure individual repositories shown in gitweb by creating file
+in the 'GIT_DIR' of git repository, or by setting some repo configuration
+variable (in 'GIT_DIR/config', see linkgit:git-config[1]).
+
+You can use the following files in repository:
+
+README.html::
+	A html file (HTML fragment) which is included on the gitweb project
+	"summary" page inside `<div>` block element. You can use it for longer
+	description of a project, to provide links (for example to project's
+	homepage), etc. This is recognized only if XSS prevention is off
+	(`$prevent_xss` is false, see linkgit:gitweb.conf[5]); a way to include
+	a README safely when XSS prevention is on may be worked out in the
+	future.
+
+description (or `gitweb.description`)::
+	Short (shortened to `$projects_list_description_width` in the projects
+	list page, which is 25 characters by default; see
+	linkgit:gitweb.conf[5]) single line description of a project (of a
+	repository).  Plain text file; HTML will be escaped.  By default set to
++
+-------------------------------------------------------------------------------
+Unnamed repository; edit this file to name it for gitweb.
+-------------------------------------------------------------------------------
++
+from the template during repository creation, usually installed in
+'/usr/share/git-core/templates/'.  You can use the `gitweb.description` repo
+configuration variable, but the file takes precedence.
+
+category (or `gitweb.category`)::
+	Singe line category of a project, used to group projects if
+	`$projects_list_group_categories` is enabled.  By default (file and
+	configuration variable absent), uncategorized projects are put in the
+	`$project_list_default_category` category.  You can use the
+	`gitweb.category` repo configuration variable, but the file takes
+	precedence.
++
+The configuration variables `$projects_list_group_categories` and
+`$project_list_default_category` are described in linkgit:gitweb.conf[5]
+
+cloneurl (or multiple-valued `gitweb.url`)::
+	File with repository URL (used for clone and fetch), one per line.
+	Displayed in the project summary page. You can use multiple-valued
+	`gitweb.url` repository configuration variable for that, but the file
+	takes precedence.
++
+This is per-repository enhancement / version of global prefix-based
+`@git_base_url_list` gitweb configuration variable (see
+linkgit:gitweb.conf[5]).
+
+gitweb.owner::
+	You can use the `gitweb.owner` repository configuration variable to set
+	repository's owner.  It is displayed in the project list and summary
+	page.
++
+If it's not set, filesystem directory's owner is used (via GECOS field,
+i.e. real name field from *getpwuid*(3)) if `$projects_list` is unset
+(gitweb scans `$projectroot` for repositories); if `$projects_list`
+points to file with list of repositories, then project owner defaults to
+value from this file for given repository.

+
+
+ACTIONS, AND URLS
+-----------------
+Gitweb can use path_info (component) based URLs, or it can pass all necessary
+information via query parameters.  The typical gitweb URLs are broken down in to
+five components:
+
+-----------------------------------------------------------------------
+.../gitweb.cgi/<repo>/<action>/<revision>:/<path>?<arguments>
+-----------------------------------------------------------------------
+
+repo::
+	The repository the action will be performed on.
++
+All actions except for those that list all available projects,
+in whatever form, require this parameter.
+
+action::
+	The action that will be run.  Defaults to 'projects_list' if repo
+	is not set, and to 'summary' otherwise.
+
+revision::
+	Revision shown.  Defaults to HEAD.
+
+path::
+	The path within the <repository> that the action is performed on,
+	for those actions that require it.
+
+arguments::
+	Any arguments that control the behaviour of the action.
+
+Some actions require or allow to specify two revisions, and sometimes even two
+pathnames.  In most general form such path_info (component) based gitweb URL
+looks like this:
+
+-----------------------------------------------------------------------
+.../gitweb.cgi/<repo>/<action>/<revision_from>:/<path_from>..<revision_to>:/<path_to>?<arguments>
+-----------------------------------------------------------------------
+
+
+Each action is implemented as a subroutine, and must be present in %actions
+hash.  Some actions are disabled by default, and must be turned on via feature
+mechanism.  For example to enable 'blame' view add the following to gitweb
+configuration file:
+
+-----------------------------------------------------------------------
+$feature{'blame'}{'default'} = [1];
+-----------------------------------------------------------------------
+
+
+Actions:
+~~~~~~~~
+The standard actions are:
+
+project_list::
+	Lists the available Git repositories.  This is the default command if no
+	repository is specified in the URL.
+
+summary::
+	Displays summary about given repository.  This is the default command if
+	no action is specified in URL, and only repository is specified.
+
+heads::
+remotes::
+	Lists all local or all remote-tracking branches in given repository.
++
+The latter is not available by default, unless configured.
+
+tags::
+	List all tags (lightweight and annotated) in given repository.
+
+blob::
+tree::
+	Shows the files and directories in a given repository path, at given
+	revision.  This is default command if no action is specified in the URL,
+	and path is given.
+
+blob_plain::
+	Returns the raw data for the file in given repository, at given path and
+	revision.  Links to this action are marked 'raw'.
+
+blobdiff::
+	Shows the difference between two revisions of the same file.
+
+blame::
+blame_incremental::
+	Shows the blame (also called annotation) information for a file. On a
+	per line basis it shows the revision in which that line was last changed
+	and the user that committed the change.  The incremental version (which
+	if configured is used automatically when JavaScript is enabled) uses
+	Ajax to incrementally add blame info to the contents of given file.
++
+This action is disabled by default for performance reasons.
+
+commit::
+commitdiff::
+	Shows information about a specific commit in a repository.  The 'commit'
+	view shows information about commit in more detail, the 'commitdiff'
+	action shows changeset for given commit.
+
+patch::
+	Returns the commit in plain text mail format, suitable for applying with
+	linkgit:git-am[1].
+
+tag::
+	Display specific annotated tag (tag object).
+
+log::
+shortlog::
+	Shows log information (commit message or just commit subject) for a
+	given branch (starting from given revision).
++
+The 'shortlog' view is more compact; it shows one commit per line.
+
+history::
+	Shows history of the file or directory in a given repository path,
+	starting from given revision (defaults to HEAD, i.e. default branch).
++
+This view is similar to 'shortlog' view.
+
+rss::
+atom::
+	Generates an RSS (or Atom) feed of changes to repository.
+
+
+WEBSERVER CONFIGURATION
+-----------------------
+This section explains how to configure some common webservers to run gitweb. In
+all cases, `/path/to/gitweb` in the examples is the directory you ran installed
+gitweb in, and contains `gitweb_config.perl`.
+
+If you've configured a web server that isn't listed here for gitweb, please send
+in the instructions so they can be included in a future release.
+
+Apache as CGI
+~~~~~~~~~~~~~
+Apache must be configured to support CGI scripts in the directory in
+which gitweb is installed.  Let's assume that it is '/var/www/cgi-bin'
+directory.
+
+-----------------------------------------------------------------------
+ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
+
+<Directory "/var/www/cgi-bin">
+    Options Indexes FollowSymlinks ExecCGI
+    AllowOverride None
+    Order allow,deny
+    Allow from all
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/cgi-bin/gitweb.cgi
+
+Apache with mod_perl, via ModPerl::Registry
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+You can use mod_perl with gitweb.  You must install Apache::Registry
+(for mod_perl 1.x) or ModPerl::Registry (for mod_perl 2.x) to enable
+this support.
+
+Assuming that gitweb is installed to '/var/www/perl', the following
+Apache configuration (for mod_perl 2.x) is suitable.
+
+-----------------------------------------------------------------------
+Alias /perl "/var/www/perl"
+
+<Directory "/var/www/perl">
+    SetHandler perl-script
+    PerlResponseHandler ModPerl::Registry
+    PerlOptions +ParseHeaders
+    Options Indexes FollowSymlinks +ExecCGI
+    AllowOverride None
+    Order allow,deny
+    Allow from all
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/perl/gitweb.cgi
+
+Apache with FastCGI
+~~~~~~~~~~~~~~~~~~~
+Gitweb works with Apache and FastCGI.  First you need to rename, copy
+or symlink gitweb.cgi to gitweb.fcgi.  Let's assume that gitweb is
+installed in '/usr/share/gitweb' directory.  The following Apache
+configuration is suitable (UNTESTED!)
+
+-----------------------------------------------------------------------
+FastCgiServer /usr/share/gitweb/gitweb.cgi
+ScriptAlias /gitweb /usr/share/gitweb/gitweb.cgi
+
+Alias /gitweb/static /usr/share/gitweb/static
+<Directory /usr/share/gitweb/static>
+    SetHandler default-handler
+</Directory>
+-----------------------------------------------------------------------
+
+With that configuration the full path to browse repositories would be:
+
+  http://server/gitweb
+
+
+ADVANCED WEB SERVER SETUP
+-------------------------
+All of those examples use request rewriting, and need `mod_rewrite`
+(or equivalent; examples below are written for Apache).
+
+Single URL for gitweb and for fetching
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you want to have one URL for both gitweb and your `http://`
+repositories, you can configure Apache like this:
+
+-----------------------------------------------------------------------
+<VirtualHost *:80>
+    ServerName    git.example.org
+    DocumentRoot  /pub/git
+    SetEnv        GITWEB_CONFIG   /etc/gitweb.conf
+
+    # turning on mod rewrite
+    RewriteEngine on
+
+    # make the front page an internal rewrite to the gitweb script
+    RewriteRule ^/$  /cgi-bin/gitweb.cgi
+
+    # make access for "dumb clients" work
+    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \
+		/cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
+</VirtualHost>
+-----------------------------------------------------------------------
+
+The above configuration expects your public repositories to live under
+'/pub/git' and will serve them as `http://git.domain.org/dir-under-pub-git`,
+both as cloneable GIT URL and as browseable gitweb interface.  If you then
+start your linkgit:git-daemon[1] with `--base-path=/pub/git --export-all`
+then you can even use the `git://` URL with exactly the same path.
+
+Setting the environment variable `GITWEB_CONFIG` will tell gitweb to use the
+named file (i.e. in this example '/etc/gitweb.conf') as a configuration for
+gitweb.  You don't really need it in above example; it is required only if
+your configuration file is in different place than built-in (during
+compiling gitweb) 'gitweb_config.perl' or '/etc/gitweb.conf'.  See
+linkgit:gitweb.conf[5] for details, especially information about precedence
+rules.
+
+If you use the rewrite rules from the example you *might* also need
+something like the following in your gitweb configuration file
+('/etc/gitweb.conf' following example):
+----------------------------------------------------------------------------
+@stylesheets = ("/some/absolute/path/gitweb.css");
+$my_uri    = "/";
+$home_link = "/";
+$per_request_config = 1;
+----------------------------------------------------------------------------
+Nowadays though gitweb should create HTML base tag when needed (to set base
+URI for relative links), so it should work automatically.
+
+
+Webserver configuration with multiple projects' root
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you want to use gitweb with several project roots you can edit your
+Apache virtual host and gitweb configuration files in the following way.
+
+The virtual host configuration (in Apache configuration file) should look
+like this:
+--------------------------------------------------------------------------
+<VirtualHost *:80>
+    ServerName    git.example.org
+    DocumentRoot  /pub/git
+    SetEnv        GITWEB_CONFIG  /etc/gitweb.conf
+
+    # turning on mod rewrite
+    RewriteEngine on
+
+    # make the front page an internal rewrite to the gitweb script
+    RewriteRule ^/$  /cgi-bin/gitweb.cgi  [QSA,L,PT]
+
+    # look for a public_git folder in unix users' home
+    # http://git.example.org/~<user>/
+    RewriteRule ^/\~([^\/]+)(/|/gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		[QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+    # http://git.example.org/+<user>/
+    #RewriteRule ^/\+([^\/]+)(/|/gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		 [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+    # http://git.example.org/user/<user>/
+    #RewriteRule ^/user/([^\/]+)/(gitweb.cgi)?$	/cgi-bin/gitweb.cgi \
+		 [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
+
+    # defined list of project roots
+    RewriteRule ^/scm(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+		[QSA,E=GITWEB_PROJECTROOT:/pub/scm/,L,PT]
+    RewriteRule ^/var(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \
+		[QSA,E=GITWEB_PROJECTROOT:/var/git/,L,PT]
+
+    # make access for "dumb clients" work
+    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \
+		/cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
+</VirtualHost>
+--------------------------------------------------------------------------
+
+Here actual project root is passed to gitweb via `GITWEB_PROJECT_ROOT`
+environment variable from a web server, so you need to put the following
+line in gitweb configuration file ('/etc/gitweb.conf' in above example):
+--------------------------------------------------------------------------
+$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git";
+--------------------------------------------------------------------------
+*Note* that this requires to be set for each request, so either
+`$per_request_config` must be false, or the above must be put in code
+referenced by `$per_request_config`;
+
+These configurations enable two things. First, each unix user (`<user>`) of
+the server will be able to browse through gitweb git repositories found in
+'~/public_git/' with the following url:
+
+  http://git.example.org/~<user>/
+
+If you do not want this feature on your server just remove the second
+rewrite rule.
+
+If you already use `mod_userdir` in your virtual host or you don't want to
+use the \'~' as first character, just comment or remove the second rewrite
+rule, and uncomment one of the following according to what you want.
+
+Second, repositories found in '/pub/scm/' and '/var/git/' will be accessible
+through `http://git.example.org/scm/` and `http://git.example.org/var/`.
+You can add as many project roots as you want by adding rewrite rules like
+the third and the fourth.
+
+
+PATH_INFO usage
+~~~~~~~~~~~~~~~
+If you enable PATH_INFO usage in gitweb by putting
+----------------------------------------------------------------------------
+$feature{'pathinfo'}{'default'} = [1];
+----------------------------------------------------------------------------
+in your gitweb configuration file, it is possible to set up your server so
+that it consumes and produces URLs in the form
+
+  http://git.example.com/project.git/shortlog/sometag
+
+i.e. without 'gitweb.cgi' part, by using a configuration such as the
+following.  This configuration assumes that '/var/www/gitweb' is the
+DocumentRoot of your webserver, contains the gitweb.cgi script and
+complementary static files (stylesheet, favicon, JavaScript):
+
+----------------------------------------------------------------------------
+<VirtualHost *:80>
+	ServerAlias git.example.com
+
+	DocumentRoot /var/www/gitweb
+
+	<Directory /var/www/gitweb>
+		Options ExecCGI
+		AddHandler cgi-script cgi
+
+		DirectoryIndex gitweb.cgi
+
+		RewriteEngine On
+		RewriteCond %{REQUEST_FILENAME} !-f
+		RewriteCond %{REQUEST_FILENAME} !-d
+		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+	</Directory>
+</VirtualHost>
+----------------------------------------------------------------------------
+The rewrite rule guarantees that existing static files will be properly
+served, whereas any other URL will be passed to gitweb as PATH_INFO
+parameter.
+
+*Notice* that in this case you don't need special settings for
+`@stylesheets`, `$my_uri` and `$home_link`, but you lose "dumb client"
+access to your project .git dirs (described in "Single URL for gitweb and
+for fetching" section).  A possible workaround for the latter is the
+following: in your project root dir (e.g. '/pub/git') have the projects
+named *without* a .git extension (e.g. '/pub/git/project' instead of
+'/pub/git/project.git') and configure Apache as follows:
+----------------------------------------------------------------------------
+<VirtualHost *:80>
+	ServerAlias git.example.com
+
+	DocumentRoot /var/www/gitweb
+
+	AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3
+	<Directory /var/www/gitweb>
+		Options ExecCGI
+		AddHandler cgi-script cgi
+
+		DirectoryIndex gitweb.cgi
+
+		RewriteEngine On
+		RewriteCond %{REQUEST_FILENAME} !-f
+		RewriteCond %{REQUEST_FILENAME} !-d
+		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+	</Directory>
+</VirtualHost>
+----------------------------------------------------------------------------
+
+The additional AliasMatch makes it so that
+
+  http://git.example.com/project.git
+
+will give raw access to the project's git dir (so that the project can be
+cloned), while
+
+  http://git.example.com/project
+
+will provide human-friendly gitweb access.
+
+This solution is not 100% bulletproof, in the sense that if some project has
+a named ref (branch, tag) starting with 'git/', then paths such as
+
+  http://git.example.com/project/command/abranch..git/abranch
+
+will fail with a 404 error.

+Subject: Using signed tag in pull requests
+Abstract: Beginning v1.7.9, a contributor can push a signed tag to her
+ publishing repository and ask her integrator to pull it. This assures the
+ integrator that the pulled history is authentic and allows others to
+ later validate it.
+Content-type: text/asciidoc
+
+Using signed tag in pull requests
+=================================
+
+A typical distributed workflow using Git is for a contributor to fork a
+project, build on it, publish the result to her public repository, and ask
+the "upstream" person (often the owner of the project where she forked
+from) to pull from her public repository. Requesting such a "pull" is made
+easy by the `git request-pull` command.
+
+Earlier, a typical pull request may have started like this:
+
+------------
+ The following changes since commit 406da78032179...:
+
+   Froboz 3.2 (2011-09-30 14:20:57 -0700)
+
+ are available in the git repository at:
+
+   example.com:/git/froboz.git for-xyzzy
+------------
+
+followed by a shortlog of the changes and a diffstat.
+
+The request was for a branch name (e.g. `for-xyzzy`) in the public
+repository of the contributor, and even though it stated where the
+contributor forked her work from, the message did not say anything about
+the commit to expect at the tip of the for-xyzzy branch. If the site that
+hosts the public repository of the contributor cannot be fully trusted, it
+was unnecessarily hard to make sure what was pulled by the integrator was
+genuinely what the contributor had produced for the project. Also there
+was no easy way for third-party auditors to later verify the resulting
+history.
+
+Starting from Git release v1.7.9, a contributor can add a signed tag to
+the commit at the tip of the history and ask the integrator to pull that
+signed tag. When the integrator runs `git pull`, the signed tag is
+automatically verified to assure that the history is not tampered with.
+In addition, the resulting merge commit records the content of the signed
+tag, so that other people can verify that the branch merged by the
+integrator was signed by the contributor, without fetching the signed tag
+used to validate the pull request separately and keeping it in the refs
+namespace.
+
+This document describes the workflow between the contributor and the
+integrator, using Git v1.7.9 or later.
+
+
+A contributor or a lieutenant
+-----------------------------
+
+After preparing her work to be pulled, the contributor uses `git tag -s`
+to create a signed tag:
+
+------------
+ $ git checkout work
+ $ ... "git pull" from sublieutenants, "git commit" your own work ...
+ $ git tag -s -m "Completed frotz feature" frotz-for-xyzzy work
+------------
+
+Note that this example uses the `-m` option to create a signed tag with
+just a one-liner message, but this is for illustration purposes only. It
+is advisable to compose a well-written explanation of what the topic does
+to justify why it is worthwhile for the integrator to pull it, as this
+message will eventually become part of the final history after the
+integrator responds to the pull request (as we will see later).
+
+Then she pushes the tag out to her public repository:
+
+------------
+ $ git push example.com:/git/froboz.git/ +frotz-for-xyzzy
+------------
+
+There is no need to push the `work` branch or anything else.
+
+Note that the above command line used a plus sign at the beginning of
+`+frotz-for-xyzzy` to allow forcing the update of a tag, as the same
+contributor may want to reuse a signed tag with the same name after the
+previous pull request has already been responded to.
+
+The contributor then prepares a message to request a "pull":
+
+------------
+ $ git request-pull v3.2 example.com:/git/froboz.git/ frotz-for-xyzzy >msg.txt
+------------
+
+The arguments are:
+
+. the version of the integrator's commit the contributor based her work on;
+. the URL of the repository, to which the contributor has pushed what she
+  wants to get pulled; and
+. the name of the tag the contributor wants to get pulled (earlier, she could
+  write only a branch name here).
+
+The resulting msg.txt file begins like so:
+
+------------
+ The following changes since commit 406da78032179...:
+
+   Froboz 3.2 (2011-09-30 14:20:57 -0700)
+
+ are available in the git repository at:
+
+   example.com:/git/froboz.git tags/frotz-for-xyzzy
+
+ for you to fetch changes up to 703f05ad5835c...:
+
+   Add tests and documentation for frotz (2011-12-02 10:02:52 -0800)
+
+ -----------------------------------------------
+ Completed frotz feature
+ -----------------------------------------------
+------------
+
+followed by a shortlog of the changes and a diffstat.  Comparing this with
+the earlier illustration of the output from the traditional `git request-pull`
+command, the reader should notice that:
+
+. The tip commit to expect is shown to the integrator; and
+. The signed tag message is shown prominently between the dashed lines
+  before the shortlog.
+
+The latter is why the contributor would want to justify why pulling her
+work is worthwhile when creating the signed tag.  The contributor then
+opens her favorite MUA, reads msg.txt, edits and sends it to her upstream
+integrator.
+
+
+Integrator
+----------
+
+After receiving such a pull request message, the integrator fetches and
+integrates the tag named in the request, with:
+
+------------
+ $ git pull example.com:/git/froboz.git/ tags/frotz-for-xyzzy
+------------
+
+This operation will always open an editor to allow the integrator to fine
+tune the commit log message when merging a signed tag.  Also, pulling a
+signed tag will always create a merge commit even when the integrator does
+not have any new commit since the contributor's work forked (i.e. 'fast
+forward'), so that the integrator can properly explain what the merge is
+about and why it was made.
+
+In the editor, the integrator will see something like this:
+
+------------
+ Merge tag 'frotz-for-xyzzy' of example.com:/git/froboz.git/
+
+ Completed frotz feature
+ # gpg: Signature made Fri 02 Dec 2011 10:03:01 AM PST using RSA key ID 96AFE6CB
+ # gpg: Good signature from "Con Tributor <nitfol@example.com>"
+------------
+
+Notice that the message recorded in the signed tag "Completed frotz
+feature" appears here, and again that is why it is important for the
+contributor to explain her work well when creating the signed tag.
+
+As usual, the lines commented with `#` are stripped out. The resulting
+commit records the signed tag used for this validation in a hidden field
+so that it can later be used by others to audit the history. There is no
+need for the integrator to keep a separate copy of the tag in his
+repository (i.e. `git tag -l` won't list the `frotz-for-xyzzy` tag in the
+above example), and there is no need to publish the tag to his public
+repository, either.
+
+After the integrator responds to the pull request and her work becomes
+part of the permanent history, the contributor can remove the tag from
+her public repository, if she chooses, in order to keep the tag namespace
+of her public repository clean, with:
+
+------------
+ $ git push example.com:/git/froboz.git :frotz-for-xyzzy
+------------
+
+
+Auditors
+--------
+
+The `--show-signature` option can be given to `git log` or `git show` and
+shows the verification status of the embedded signed tag in merge commits
+created when the integrator responded to a pull request of a signed tag.
+
+A typical output from `git show --show-signature` may look like this:
+
+------------
+ $ git show --show-signature
+ commit 02306ef6a3498a39118aef9df7975bdb50091585
+ merged tag 'frotz-for-xyzzy'
+ gpg: Signature made Fri 06 Jan 2012 12:41:49 PM PST using RSA key ID 96AFE6CB
+ gpg: Good signature from "Con Tributor <nitfol@example.com>"

+argv-array API
+==============
+
+The argv-array API allows one to dynamically build and store
+NULL-terminated lists.  An argv-array maintains the invariant that the
+`argv` member always points to a non-NULL array, and that the array is
+always NULL-terminated at the element pointed to by `argv[argc]`. This
+makes the result suitable for passing to functions expecting to receive
+argv from main(), or the link:api-run-command.html[run-command API].
+
+The link:api-string-list.html[string-list API] is similar, but cannot be
+used for these purposes; instead of storing a straight string pointer,
+it contains an item structure with a `util` field that is not compatible
+with the traditional argv interface.
+
+Each `argv_array` manages its own memory. Any strings pushed into the
+array are duplicated, and all memory is freed by argv_array_clear().
+
+Data Structures
+---------------
+
+`struct argv_array`::
+
+	A single array. This should be initialized by assignment from
+	`ARGV_ARRAY_INIT`, or by calling `argv_array_init`. The `argv`
+	member contains the actual array; the `argc` member contains the
+	number of elements in the array, not including the terminating
+	NULL.
+
+Functions
+---------
+
+`argv_array_init`::
+	Initialize an array. This is no different than assigning from

+config API
+==========
+
+The config API gives callers a way to access git configuration files
+(and files which have the same syntax). See linkgit:git-config[1] for a
+discussion of the config file syntax.
+
+General Usage
+-------------
+
+Config files are parsed linearly, and each variable found is passed to a
+caller-provided callback function. The callback function is responsible
+for any actions to be taken on the config option, and is free to ignore
+some options. It is not uncommon for the configuration to be parsed
+several times during the run of a git program, with different callbacks
+picking out different variables useful to themselves.
+
+A config callback function takes three parameters:
+
+- the name of the parsed variable. This is in canonical "flat" form: the
+  section, subsection, and variable segments will be separated by dots,
+  and the section and variable segments will be all lowercase. E.g.,
+  `core.ignorecase`, `diff.SomeType.textconv`.
+
+- the value of the found variable, as a string. If the variable had no
+  value specified, the value will be NULL (typically this means it
+  should be interpreted as boolean true).
+
+- a void pointer passed in by the caller of the config API; this can
+  contain callback-specific data
+
+A config callback should return 0 for success, or -1 if the variable
+could not be parsed properly.
+
+Basic Config Querying
+---------------------
+
+Most programs will simply want to look up variables in all config files
+that git knows about, using the normal precedence rules. To do this,
+call `git_config` with a callback function and void data pointer.
+
+`git_config` will read all config sources in order of increasing
+priority. Thus a callback should typically overwrite previously-seen
+entries with new ones (e.g., if both the user-wide `~/.gitconfig` and
+repo-specific `.git/config` contain `color.ui`, the config machinery
+will first feed the user-wide one to the callback, and then the
+repo-specific one; by overwriting, the higher-priority repo-specific
+value is left at the end).
+
+The `git_config_with_options` function lets the caller examine config
+while adjusting some of the default behavior of `git_config`. It should
+almost never be used by "regular" git code that is looking up
+configuration variables. It is intended for advanced callers like
+`git-config`, which are intentionally tweaking the normal config-lookup
+process. It takes two extra parameters:
+
+`filename`::
+If this parameter is non-NULL, it specifies the name of a file to
+parse for configuration, rather than looking in the usual files. Regular
+`git_config` defaults to `NULL`.
+
+`respect_includes`::
+Specify whether include directives should be followed in parsed files.
+Regular `git_config` defaults to `1`.
+
+There is a special version of `git_config` called `git_config_early`.
+This version takes an additional parameter to specify the repository
+config, instead of having it looked up via `git_path`. This is useful
+early in a git program before the repository has been found. Unless
+you're working with early setup code, you probably don't want to use
+this.
+
+Reading Specific Files
+----------------------
+
+To read a specific file in git-config format, use
+`git_config_from_file`. This takes the same callback and data parameters
+as `git_config`.
+
+Value Parsing Helpers
+---------------------
+
+To aid in parsing string values, the config API provides callbacks with
+a number of helper functions, including:
+
+`git_config_int`::
+Parse the string to an integer, including unit factors. Dies on error;
+otherwise, returns the parsed result.
+
+`git_config_ulong`::
+Identical to `git_config_int`, but for unsigned longs.
+
+`git_config_bool`::
+Parse a string into a boolean value, respecting keywords like "true" and
+"false". Integer values are converted into true/false values (when they
+are non-zero or zero, respectively). Other values cause a die(). If
+parsing is successful, the return value is the result.
+
+`git_config_bool_or_int`::
+Same as `git_config_bool`, except that integers are returned as-is, and
+an `is_bool` flag is unset.
+
+`git_config_maybe_bool`::
+Same as `git_config_bool`, except that it returns -1 on error rather
+than dying.
+
+`git_config_string`::
+Allocates and copies the value string into the `dest` parameter; if no
+string is given, prints an error message and returns -1.
+
+`git_config_pathname`::
+Similar to `git_config_string`, but expands `~` or `~user` into the
+user's home directory when found at the beginning of the path.
+
+Include Directives
+------------------
+
+By default, the config parser does not respect include directives.
+However, a caller can use the special `git_config_include` wrapper
+callback to support them. To do so, you simply wrap your "real" callback
+function and data pointer in a `struct config_include_data`, and pass
+the wrapper to the regular config-reading functions. For example:
+
+-------------------------------------------
+int read_file_with_include(const char *file, config_fn_t fn, void *data)
+{
+	struct config_include_data inc = CONFIG_INCLUDE_INIT;
+	inc.fn = fn;
+	inc.data = data;
+	return git_config_from_file(git_config_include, file, &inc);
+}
+-------------------------------------------
+
+`git_config` respects includes automatically. The lower-level
+`git_config_from_file` does not.

+credentials API
+===============
+
+The credentials API provides an abstracted way of gathering username and
+password credentials from the user (even though credentials in the wider
+world can take many forms, in this document the word "credential" always
+refers to a username and password pair).
+
+This document describes two interfaces: the C API that the credential
+subsystem provides to the rest of git, and the protocol that git uses to
+communicate with system-specific "credential helpers". If you are
+writing git code that wants to look up or prompt for credentials, see
+the section "C API" below. If you want to write your own helper, see
+the section on "Credential Helpers" below.
+
+Typical setup
+-------------
+
+------------
++-----------------------+
+| git code (C)          |--- to server requiring --->
+|                       |        authentication
+|.......................|
+| C credential API      |--- prompt ---> User
++-----------------------+
+	^      |
+	| pipe |
+	|      v
++-----------------------+
+| git credential helper |
++-----------------------+
+------------
+
+The git code (typically a remote-helper) will call the C API to obtain
+credential data like a login/password pair (credential_fill). The
+API will itself call a remote helper (e.g. "git credential-cache" or
+"git credential-store") that may retrieve credential data from a
+store. If the credential helper cannot find the information, the C API
+will prompt the user. Then, the caller of the API takes care of
+contacting the server, and does the actual authentication.
+
+C API
+-----
+
+The credential C API is meant to be called by git code which needs to
+acquire or store a credential. It is centered around an object
+representing a single credential and provides three basic operations:
+fill (acquire credentials by calling helpers and/or prompting the user),
+approve (mark a credential as successfully used so that it can be stored
+for later use), and reject (mark a credential as unsuccessful so that it
+can be erased from any persistent storage).
+
+Data Structures
+~~~~~~~~~~~~~~~
+
+`struct credential`::
+
+	This struct represents a single username/password combination
+	along with any associated context. All string fields should be
+	heap-allocated (or NULL if they are not known or not applicable).
+	The meaning of the individual context fields is the same as
+	their counterparts in the helper protocol; see the section below
+	for a description of each field.
++
+The `helpers` member of the struct is a `string_list` of helpers.  Each
+string specifies an external helper which will be run, in order, to
+either acquire or store credentials. See the section on credential
+helpers below. This list is filled-in by the API functions
+according to the corresponding configuration variables before
+consulting helpers, so there usually is no need for a caller to
+modify the helpers field at all.
++
+This struct should always be initialized with `CREDENTIAL_INIT` or
+`credential_init`.
+
+
+Functions
+~~~~~~~~~
+
+`credential_init`::
+
+	Initialize a credential structure, setting all fields to empty.
+
+`credential_clear`::
+
+	Free any resources associated with the credential structure,
+	returning it to a pristine initialized state.
+
+`credential_fill`::
+
+	Instruct the credential subsystem to fill the username and
+	password fields of the passed credential struct by first
+	consulting helpers, then asking the user. After this function
+	returns, the username and password fields of the credential are
+	guaranteed to be non-NULL. If an error occurs, the function will
+	die().
+
+`credential_reject`::
+
+	Inform the credential subsystem that the provided credentials
+	have been rejected. This will cause the credential subsystem to
+	notify any helpers of the rejection (which allows them, for
+	example, to purge the invalid credentials from storage).  It
+	will also free() the username and password fields of the
+	credential and set them to NULL (readying the credential for
+	another call to `credential_fill`). Any errors from helpers are
+	ignored.
+
+`credential_approve`::
+
+	Inform the credential subsystem that the provided credentials
+	were successfully used for authentication.  This will cause the
+	credential subsystem to notify any helpers of the approval, so
+	that they may store the result to be used again.  Any errors
+	from helpers are ignored.
+
+`credential_from_url`::
+
+	Parse a URL into broken-down credential fields.
+
+Example
+~~~~~~~
+
+The example below shows how the functions of the credential API could be
+used to login to a fictitious "foo" service on a remote host:
+
+-----------------------------------------------------------------------
+int foo_login(struct foo_connection *f)
+{
+	int status;
+	/*
+	 * Create a credential with some context; we don't yet know the
+	 * username or password.
+	 */
+
+	struct credential c = CREDENTIAL_INIT;
+	c.protocol = xstrdup("foo");
+	c.host = xstrdup(f->hostname);
+
+	/*
+	 * Fill in the username and password fields by contacting
+	 * helpers and/or asking the user. The function will die if it
+	 * fails.
+	 */
+	credential_fill(&c);
+
+	/*
+	 * Otherwise, we have a username and password. Try to use it.
+	 */
+	status = send_foo_login(f, c.username, c.password);
+	switch (status) {
+	case FOO_OK:
+		/* It worked. Store the credential for later use. */
+		credential_accept(&c);
+		break;
+	case FOO_BAD_LOGIN:
+		/* Erase the credential from storage so we don't try it
+		 * again. */
+		credential_reject(&c);
+		break;
+	default:
+		/*
+		 * Some other error occured. We don't know if the
+		 * credential is good or bad, so report nothing to the
+		 * credential subsystem.
+		 */
+	}
+
+	/* Free any associated resources. */
+	credential_clear(&c);
+
+	return status;
+}
+-----------------------------------------------------------------------
+
+
+Credential Helpers
+------------------
+
+Credential helpers are programs executed by git to fetch or save
+credentials from and to long-term storage (where "long-term" is simply
+longer than a single git process; e.g., credentials may be stored
+in-memory for a few minutes, or indefinitely on disk).
+
+Each helper is specified by a single string in the configuration
+variable `credential.helper` (and others, see linkgit:git-config[1]).
+The string is transformed by git into a command to be executed using
+these rules:
+
+  1. If the helper string begins with "!", it is considered a shell
+     snippet, and everything after the "!" becomes the command.
+
+  2. Otherwise, if the helper string begins with an absolute path, the
+     verbatim helper string becomes the command.
+
+  3. Otherwise, the string "git credential-" is prepended to the helper
+     string, and the result becomes the command.
+
+The resulting command then has an "operation" argument appended to it
+(see below for details), and the result is executed by the shell.
+
+Here are some example specifications:
+
+----------------------------------------------------
+# run "git credential-foo"
+foo
+
+# same as above, but pass an argument to the helper
+foo --bar=baz
+
+# the arguments are parsed by the shell, so use shell
+# quoting if necessary
+foo --bar="whitespace arg"
+
+# you can also use an absolute path, which will not use the git wrapper
+/path/to/my/helper --with-arguments
+
+# or you can specify your own shell snippet
+!f() { echo "password=`cat $HOME/.secret`"; }; f
+----------------------------------------------------
+
+Generally speaking, rule (3) above is the simplest for users to specify.
+Authors of credential helpers should make an effort to assist their
+users by naming their program "git-credential-$NAME", and putting it in
+the $PATH or $GIT_EXEC_PATH during installation, which will allow a user
+to enable it with `git config credential.helper $NAME`.
+
+When a helper is executed, it will have one "operation" argument
+appended to its command line, which is one of:
+
+`get`::
+
+	Return a matching credential, if any exists.
+
+`store`::
+
+	Store the credential, if applicable to the helper.
+
+`erase`::
+
+	Remove a matching credential, if any, from the helper's storage.
+
+The details of the credential will be provided on the helper's stdin
+stream. The credential is split into a set of named attributes.
+Attributes are provided to the helper, one per line. Each attribute is
+specified by a key-value pair, separated by an `=` (equals) sign,
+followed by a newline. The key may contain any bytes except `=`,
+newline, or NUL. The value may contain any bytes except newline or NUL.
+In both cases, all bytes are treated as-is (i.e., there is no quoting,
+and one cannot transmit a value with newline or NUL in it). The list of
+attributes is terminated by a blank line or end-of-file.
+
+Git will send the following attributes (but may not send all of
+them for a given credential; for example, a `host` attribute makes no
+sense when dealing with a non-network protocol):
+
+`protocol`::
+
+	The protocol over which the credential will be used (e.g.,
+	`https`).
+
+`host`::
+
+	The remote hostname for a network credential.
+
+`path`::
+
+	The path with which the credential will be used. E.g., for
+	accessing a remote https repository, this will be the
+	repository's path on the server.
+
+`username`::
+
+	The credential's username, if we already have one (e.g., from a
+	URL, from the user, or from a previously run helper).
+
+`password`::
+
+	The credential's password, if we are asking it to be stored.
+
+For a `get` operation, the helper should produce a list of attributes
+on stdout in the same format. A helper is free to produce a subset, or
+even no values at all if it has nothing useful to provide. Any provided
+attributes will overwrite those already known about by git.
+
+For a `store` or `erase` operation, the helper's output is ignored.
+If it fails to perform the requested operation, it may complain to
+stderr to inform the user. If it does not support the requested
+operation (e.g., a read-only store), it should silently ignore the
+request.
+
+If a helper receives any other operation, it should silently ignore the
+request. This leaves room for future operations to be added (older
+helpers will just ignore the new requests).

+sha1-array API
+==============
+
+The sha1-array API provides storage and manipulation of sets of SHA1
+identifiers. The emphasis is on storage and processing efficiency,
+making them suitable for large lists. Note that the ordering of items is
+not preserved over some operations.
+
+Data Structures
+---------------
+
+`struct sha1_array`::
+
+	A single array of SHA1 hashes. This should be initialized by
+	assignment from `SHA1_ARRAY_INIT`.  The `sha1` member contains
+	the actual data. The `nr` member contains the number of items in
+	the set.  The `alloc` and `sorted` members are used internally,
+	and should not be needed by API callers.
+
+Functions
+---------
+
+`sha1_array_append`::
+	Add an item to the set. The sha1 will be placed at the end of
+	the array (but note that some operations below may lose this
+	ordering).
+
+`sha1_array_sort`::
+	Sort the elements in the array.
+
+`sha1_array_lookup`::
+	Perform a binary search of the array for a specific sha1.
+	If found, returns the offset (in number of elements) of the
+	sha1. If not found, returns a negative integer. If the array is
+	not sorted, this function has the side effect of sorting it.
+
+`sha1_array_clear`::
+	Free all memory associated with the array and return it to the
+	initial, empty state.
+
+`sha1_array_for_each_unique`::
+	Efficiently iterate over each unique element of the list,
+	executing the callback function for each one. If the array is
+	not sorted, this function has the side effect of sorting it.
+
+Examples
+--------
+
+-----------------------------------------
+void print_callback(const unsigned char sha1[20],
+		    void *data)
+{
+	printf("%s\n", sha1_to_hex(sha1));
+}
+
+void some_func(void)
+{
+	struct sha1_array hashes = SHA1_ARRAY_INIT;
+	unsigned char sha1[20];
+
+	/* Read objects into our set */
+	while (read_object_from_stdin(sha1))
+		sha1_array_append(&hashes, sha1);
+
+	/* Check if some objects are in our set */
+	while (read_object_from_stdin(sha1)) {
+		if (sha1_array_lookup(&hashes, sha1) >= 0)
+			printf("it's in there!\n");
+
+	/*
+	 * Print the unique set of objects. We could also have
+	 * avoided adding duplicate objects in the first place,
+	 * but we would end up re-sorting the array repeatedly.
+	 * Instead, this will sort once and then skip duplicates
+	 * in linear time.

 which is a few percent faster on CPU intensive workloads.  This
 may be a good tradeoff for distribution packagers.
 
-Note that the profile feedback build stage currently generates
-a lot of additional compiler warnings.
+Or if you just want to install a profile-optimized version of git into
+your home directory, you could run:
+
+	$ make PROFILE=BUILD install
+
+As a caveat: a profile-optimized build takes a *lot* longer since the
+git tree must be built twice, and in order for the profiling
+measurements to work properly, ccache must be disabled and the test
+suite has to be run using only a single CPU.  In addition, the profile
+feedback build stage currently generates a lot of additional compiler
+warnings.

+diff-highlight
+==============
+
+Line oriented diffs are great for reviewing code, because for most
+hunks, you want to see the old and the new segments of code next to each
+other. Sometimes, though, when an old line and a new line are very
+similar, it's hard to immediately see the difference.
+
+You can use "--color-words" to highlight only the changed portions of
+lines. However, this can often be hard to read for code, as it loses
+the line structure, and you end up with oddly formatted bits.
+
+Instead, this script post-processes the line-oriented diff, finds pairs
+of lines, and highlights the differing segments.  It's currently very
+simple and stupid about doing these tasks. In particular:
+
+  1. It will only highlight hunks in which the number of removed and
+     added lines is the same, and it will pair lines within the hunk by
+     position (so the first removed line is compared to the first added
+     line, and so forth). This is simple and tends to work well in
+     practice. More complex changes don't highlight well, so we tend to
+     exclude them due to the "same number of removed and added lines"
+     restriction. Or even if we do try to highlight them, they end up
+     not highlighting because of our "don't highlight if the whole line
+     would be highlighted" rule.
+
+  2. It will find the common prefix and suffix of two lines, and
+     consider everything in the middle to be "different". It could
+     instead do a real diff of the characters between the two lines and
+     find common subsequences. However, the point of the highlight is to
+     call attention to a certain area. Even if some small subset of the
+     highlighted area actually didn't change, that's OK. In practice it
+     ends up being more readable to just have a single blob on the line
+     showing the interesting bit.
+
+The goal of the script is therefore not to be exact about highlighting
+changes, but to call attention to areas of interest without being
+visually distracting.  Non-diff lines and existing diff coloration is
+preserved; the intent is that the output should look exactly the same as
+the input, except for the occasional highlight.
+
+Use
+---
+
+You can try out the diff-highlight program with:
+
+---------------------------------------------
+git log -p --color | /path/to/diff-highlight
+---------------------------------------------
+
+If you want to use it all the time, drop it in your $PATH and put the
+following in your git configuration:
+
+---------------------------------------------
+[pager]
+	log = diff-highlight | less
+	show = diff-highlight | less
+	diff = diff-highlight | less
+---------------------------------------------
+
+Bugs
+----
+
+Because diff-highlight relies on heuristics to guess which parts of
+changes are important, there are some cases where the highlighting is
+more distracting than useful. Fortunately, these cases are rare in
+practice, and when they do occur, the worst case is simply a little
+extra highlighting. This section documents some cases known to be
+sub-optimal, in case somebody feels like working on improving the
+heuristics.
+
+1. Two changes on the same line get highlighted in a blob. For example,
+   highlighting:
+
+----------------------------------------------
+-foo(buf, size);
++foo(obj->buf, obj->size);
+----------------------------------------------
+
+   yields (where the inside of "+{}" would be highlighted):
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->buf, obj->}size);
+----------------------------------------------
+
+   whereas a more semantically meaningful output would be:
+
+----------------------------------------------
+-foo(buf, size);
++foo(+{obj->}buf, +{obj->}size);
+----------------------------------------------
+
+   Note that doing this right would probably involve a set of
+   content-specific boundary patterns, similar to word-diff. Otherwise
+   you get junk like:
+
+-----------------------------------------------------
+-this line has some -{i}nt-{ere}sti-{ng} text on it
++this line has some +{fa}nt+{a}sti+{c} text on it
+-----------------------------------------------------
+
+   which is less readable than the current output.
+
+2. The multi-line matching assumes that lines in the pre- and post-image
+   match by position. This is often the case, but can be fooled when a
+   line is removed from the top and a new one added at the bottom (or
+   vice versa). Unless the lines in the middle are also changed, diffs
+   will show this as two hunks, and it will not get highlighted at all
+   (which is good). But if the lines in the middle are changed, the
+   highlighting can be misleading. Here's a pathological case:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two 2
++three 3
++four 4
++five 5
+-----------------------------------------------------
+
+   which gets highlighted as:
+
+-----------------------------------------------------
+-one
+-t-{wo}
+-three
+-f-{our}
++two 2
++t+{hree 3}
++four 4
++f+{ive 5}
+-----------------------------------------------------
+
+   because it matches "two" to "three 3", and so forth. It would be
+   nicer as:
+
+-----------------------------------------------------
+-one
+-two
+-three
+-four
++two +{2}
++three +{3}
++four +{4}
++five 5
+-----------------------------------------------------
+
+   which would probably involve pre-matching the lines into pairs
+   according to some heuristic.

+The git-diffall script provides a directory based diff mechanism
+for git.
+
+To determine what diff viewer is used, the script requires either
+the 'diff.tool' or 'merge.tool' configuration option to be set.
+
+This script is compatible with most common forms used to specify a
+range of revisions to diff:
+
+  1. git diffall: shows diff between working tree and staged changes
+  2. git diffall --cached [<commit>]: shows diff between staged
+     changes and HEAD (or other named commit)
+  3. git diffall <commit>: shows diff between working tree and named
+     commit
+  4. git diffall <commit> <commit>: show diff between two named commits
+  5. git diffall <commit>..<commit>: same as above
+  6. git diffall <commit>...<commit>: show the changes on the branch
+     containing and up to the second, starting at a common ancestor
+     of both <commit>
+
+Note: all forms take an optional path limiter [-- <path>*]
+
+The '--extcmd=<command>' option allows the user to specify a custom
+command for viewing diffs.  When given, configured defaults are
+ignored and the script runs $command $LOCAL $REMOTE.  Additionally,
+$BASE is set in the environment.
+
+This script is based on an example provided by Thomas Rast on the
+Git list [1]:

-git-p4 - Perforce <-> Git converter using git-fast-import
-
-Usage
-=====
-
-git-p4 can be used in two different ways:
-
-1) To import changes from Perforce to a Git repository, using "git-p4 sync".
-
-2) To submit changes from Git back to Perforce, using "git-p4 submit".
-
-Importing
-=========
-
-Simply start with
-
-  git-p4 clone //depot/path/project
-
-or
-
-  git-p4 clone //depot/path/project myproject
-
-This will:
-
-1) Create an empty git repository in a subdirectory called "project" (or
-"myproject" with the second command)
-
-2) Import the head revision from the given Perforce path into a git branch
-called "p4" (remotes/p4 actually)
-
-3) Create a master branch based on it and check it out.
-
-If you want the entire history (not just the head revision) then you can simply
-append a "@all" to the depot path:
-
-  git-p4 clone //depot/project/main@all myproject
-
-
-
-If you want more control you can also use the git-p4 sync command directly:
-
-  mkdir repo-git
-  cd repo-git
-  git init
-  git-p4 sync //path/in/your/perforce/depot
-
-This will import the current head revision of the specified depot path into a
-"remotes/p4/master" branch of your git repository. You can use the
---branch=mybranch option to import into a different branch.
-
-If you want to import the entire history of a given depot path simply use:
-
-  git-p4 sync //path/in/depot@all
-
-
-Note:
-
-To achieve optimal compression you may want to run 'git repack -a -d -f' after
-a big import. This may take a while.
-
-Incremental Imports
-===================
-
-After an initial import you can continue to synchronize your git repository
-with newer changes from the Perforce depot by just calling
-
-  git-p4 sync
-
-in your git repository. By default the "remotes/p4/master" branch is updated.
-
-Advanced Setup
-==============
-
-Suppose you have a periodically updated git repository somewhere, containing a
-complete import of a Perforce project. This repository can be cloned and used
-with git-p4. When updating the cloned repository with the "sync" command,
-git-p4 will try to fetch changes from the original repository first. The git
-protocol used with this is usually faster than importing from Perforce
-directly.
-
-This behaviour can be disabled by setting the "git-p4.syncFromOrigin" git
-configuration variable to "false".
-
-Updating
-========
-
-A common working pattern is to fetch the latest changes from the Perforce depot
-and merge them with local uncommitted changes. The recommended way is to use
-git's rebase mechanism to preserve linear history. git-p4 provides a convenient
-
-  git-p4 rebase
-
-command that calls git-p4 sync followed by git rebase to rebase the current
-working branch.
-
-Submitting
-==========
-
-git-p4 has support for submitting changes from a git repository back to the
-Perforce depot. This requires a Perforce checkout separate from your git
-repository. To submit all changes that are in the current git branch but not in
-the "p4" branch (or "origin" if "p4" doesn't exist) simply call
-
-    git-p4 submit
-
-in your git repository. If you want to submit changes in a specific branch that
-is not your current git branch you can also pass that as an argument:
-
-    git-p4 submit mytopicbranch
-
-You can override the reference branch with the --origin=mysourcebranch option.
-
-The Perforce changelists will be created with the user who ran git-p4. If you
-use --preserve-user then git-p4 will attempt to create Perforce changelists
-with the Perforce user corresponding to the git commit author. You need to
-have sufficient permissions within Perforce, and the git users need to have
-Perforce accounts. Permissions can be granted using 'p4 protect'.
-
-If a submit fails you may have to "p4 resolve" and submit manually. You can
-continue importing the remaining changes with
-
-  git-p4 submit --continue
-
-Example
-=======
-
-# Clone a repository
-  git-p4 clone //depot/path/project
-# Enter the newly cloned directory
-  cd project
-# Do some work...
-  vi foo.h
-# ... and commit locally to gi
-  git commit foo.h
-# In the meantime somebody submitted changes to the Perforce depot. Rebase your latest
-# changes against the latest changes in Perforce:
-  git-p4 rebase
-# Submit your locally committed changes back to Perforce
-  git-p4 submit
-# ... and synchronize with Perforce
-  git-p4 rebase
-
-
-Configuration parameters
-========================
-
-git-p4.user ($P4USER)
-
-Allows you to specify the username to use to connect to the Perforce repository.
-
-  git config [--global] git-p4.user public
-
-git-p4.password ($P4PASS)
-
-Allows you to specify the password to use to connect to the Perforce repository.
-Warning this password will be visible on the command-line invocation of the p4 binary.
-
-  git config [--global] git-p4.password public1234
-
-git-p4.port ($P4PORT)
-
-Specify the port to be used to contact the Perforce server. As this will be passed
-directly to the p4 binary, it may be in the format host:port as well.
-
-  git config [--global] git-p4.port codes.zimbra.com:2666
-
-git-p4.host ($P4HOST)
-
-Specify the host to contact for a Perforce repository.
-
-  git config [--global] git-p4.host perforce.example.com
-
-git-p4.client ($P4CLIENT)
-
-Specify the client name to use
-
-  git config [--global] git-p4.client public-view
-
-git-p4.allowSubmit
-
-  git config [--global] git-p4.allowSubmit false
-
-git-p4.syncFromOrigin
-
-A useful setup may be that you have a periodically updated git repository
-somewhere that contains a complete import of a Perforce project. That git
-repository can be used to clone the working repository from and one would
-import from Perforce directly after cloning using git-p4. If the connection to
-the Perforce server is slow and the working repository hasn't been synced for a
-while it may be desirable to fetch changes from the origin git repository using
-the efficient git protocol. git-p4 supports this setup by calling "git fetch origin"
-by default if there is an origin branch. You can disable this using:
-
-  git config [--global] git-p4.syncFromOrigin false
-
-git-p4.useclientspec
-
-  git config [--global] git-p4.useclientspec false
-
-The P4CLIENT environment variable should be correctly set for p4 to be
-able to find the relevant client.  This client spec will be used to
-both filter the files cloned by git and set the directory layout as
-specified in the client (this implies --keep-path style semantics).
-
-git-p4.skipSubmitModTimeCheck
-
-  git config [--global] git-p4.skipSubmitModTimeCheck false
-
-If true, submit will not check if the p4 change template has been modified.
-
-git-p4.preserveUser
-
-  git config [--global] git-p4.preserveUser false
-
-If true, attempt to preserve user names by modifying the p4 changelists. See
-the "--preserve-user" submit option.
-
-git-p4.allowMissingPerforceUsers
-
-  git config [--global] git-p4.allowMissingP4Users false
-
-If git-p4 is setting the perforce user for a commit (--preserve-user) then
-if there is no perforce user corresponding to the git author, git-p4 will
-stop. With allowMissingPerforceUsers set to true, git-p4 will use the
-current user (i.e. the behavior without --preserve-user) and carry on with
-the perforce commit.
-
-git-p4.skipUserNameCheck
-
-  git config [--global] git-p4.skipUserNameCheck false
-
-When submitting, git-p4 checks that the git commits are authored by the current
-p4 user, and warns if they are not. This disables the check.
-
-git-p4.detectRenames
-
-Detect renames when submitting changes to Perforce server. Will enable -M git
-argument. Can be optionally set to a number representing the threshold
-percentage value of the rename detection.
-
-  git config [--global] git-p4.detectRenames true
-  git config [--global] git-p4.detectRenames 50
-
-git-p4.detectCopies
-
-Detect copies when submitting changes to Perforce server. Will enable -C git
-argument. Can be optionally set to a number representing the threshold
-percentage value of the copy detection.
-
-  git config [--global] git-p4.detectCopies true
-  git config [--global] git-p4.detectCopies 80
-
-git-p4.detectCopiesHarder
-
-Detect copies even between files that did not change when submitting changes to
-Perforce server. Will enable --find-copies-harder git argument.
-
-  git config [--global] git-p4.detectCopies true
-
-git-p4.branchUser
-
-Only use branch specifications defined by the selected username.
-
-  git config [--global] git-p4.branchUser username
-
-git-p4.branchList
-
-List of branches to be imported when branch detection is enabled.
-
-  git config [--global] git-p4.branchList main:branchA
-  git config [--global] --add git-p4.branchList main:branchB
-
-Implementation Details...
-=========================
-
-* Changesets from Perforce are imported using git fast-import.
-* The import does not require anything from the Perforce client view as it just uses
-  "p4 print //depot/path/file#revision" to get the actual file contents.
-* Every imported changeset has a special [git-p4...] line at the
-  end of the log message that gives information about the corresponding
-  Perforce change number and is also used by git-p4 itself to find out
-  where to continue importing when doing incremental imports.
-  Basically when syncing it extracts the perforce change number of the
-  latest commit in the "p4" branch and uses "p4 changes //depot/path/...@changenum,#head"
-  to find out which changes need to be imported.
-* git-p4 submit uses "git rev-list" to pick the commits between the "p4" branch
-  and the current branch.
-  The commits themselves are applied using git diff/format-patch ... | git apply

+git-jump
+========
+
+Git-jump is a script for helping you jump to "interesting" parts of your
+project in your editor. It works by outputting a set of interesting
+spots in the "quickfix" format, which editors like vim can use as a
+queue of places to visit (this feature is usually used to jump to errors
+produced by a compiler). For example, given a diff like this:
+
+------------------------------------
+diff --git a/foo.c b/foo.c
+index a655540..5a59044 100644
+--- a/foo.c
++++ b/foo.c
+@@ -1,3 +1,3 @@
+ int main(void) {
+-  printf("hello word!\n");
++  printf("hello world!\n");
+ }
+-----------------------------------
+
+git-jump will feed this to the editor:
+
+-----------------------------------
+foo.c:2: printf("hello word!\n");
+-----------------------------------
+
+Obviously this trivial case isn't that interesting; you could just open
+`foo.c` yourself. But when you have many changes scattered across a
+project, you can use the editor's support to "jump" from point to point.
+
+Git-jump can generate three types of interesting lists:
+
+  1. The beginning of any diff hunks.
+
+  2. The beginning of any merge conflict markers.
+
+  3. Any grep matches.
+
+
+Using git-jump
+--------------
+
+To use it, just drop git-jump in your PATH, and then invoke it like
+this:
+
+--------------------------------------------------
+# jump to changes not yet staged for commit
+git jump diff
+
+# jump to changes that are staged for commit; you can give
+# arbitrary diff options
+git jump diff --cached
+
+# jump to merge conflicts
+git jump merge
+
+# jump to all instances of foo_bar
+git jump grep foo_bar
+
+# same as above, but case-insensitive; you can give
+# arbitrary grep options
+git jump grep -i foo_bar
+--------------------------------------------------
+
+
+Related Programs
+----------------
+
+You can accomplish some of the same things with individual tools. For
+example, you can use `git mergetool` to start vimdiff on each unmerged
+file. `git jump merge` is for the vim-wielding luddite who just wants to
+jump straight to the conflict text with no fanfare.
+
+As of git v1.7.2, `git grep` knows the `--open-files-in-pager` option,
+which does something similar to `git jump grep`. However, it is limited
+to positioning the cursor to the correct line in only the first file,
+leaving you to locate subsequent hits in that file or other files using
+the editor or pager. By contrast, git-jump provides the editor with a
+complete list of files and line numbers for each match.
+
+
+Limitations
+-----------
+
+This scripts was written and tested with vim. Given that the quickfix
+format is the same as what gcc produces, I expect emacs users have a
+similar feature for iterating through the list, but I know nothing about
+how to activate it.
+
+The shell snippets to generate the quickfix lines will almost certainly
+choke on filenames with exotic characters (like newlines).

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+git-remote-persistent-https
+
+The git-remote-persistent-https binary speeds up SSL operations
+by running a daemon job (git-remote-persistent-https--proxy) that
+keeps a connection open to a server.
+
+
+PRE-BUILT BINARIES
+
+Darwin amd64:
+https://commondatastorage.googleapis.com/git-remote-persistent-https/darwin_amd64.tar.gz
+
+Linux amd64:
+https://commondatastorage.googleapis.com/git-remote-persistent-https/linux_amd64.tar.gz
+
+
+INSTALLING
+
+Move all of the git-remote-persistent-http* binaries to a directory
+in PATH.
+
+
+USAGE
+
+HTTPS requests can be delegated to the proxy by using the
+"persistent-https" scheme, e.g.
+
+git clone persistent-https://kernel.googlesource.com/pub/scm/git/git
+
+Likewise, .gitconfig can be updated as follows to rewrite https urls
+to use persistent-https:
+
+[url "persistent-https"]
+	insteadof = https
+[url "persistent-http"]
+	insteadof = http
+
+
+#####################################################################
+# BUILDING FROM SOURCE
+#####################################################################
+
+LOCATION
+
+The source is available in the contrib/persistent-https directory of
+the Git source repository. The Git source repository is available at
+git://git.kernel.org/pub/scm/git/git.git/
+https://kernel.googlesource.com/pub/scm/git/git
+
+
+PREREQUISITES
+
+The code is written in Go (http://golang.org/) and the Go compiler is
+required. Currently, the compiler must be built and installed from tip
+of source, in order to include a fix in the reverse http proxy:
+http://code.google.com/p/go/source/detail?r=a615b796570a2cd8591884767a7d67ede74f6648
+
+
+BUILDING
+
+Run "make" to build the binaries. See the section on
+INSTALLING above.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+HOW TO INSTALL git-subtree
+==========================
+
+First, build from the top source directory.
+
+Then, in contrib/subtree, run:
+
+  make
+  make install
+  make install-doc
+
+If you used configure to do the main build the git-subtree build will
+pick up those settings.  If not, you will likely have to provide a
+value for prefix:
+
+  make prefix=<some dir>
+  make prefix=<some dir> install
+  make prefix=<some dir> install-doc
+
+To run tests first copy git-subtree to the main build area so the
+newly-built git can find it:
+
+  cp git-subtree ../..
+
+Then:
+
+  make test
+

+NAME
+----
+git-subtree - Merge subtrees together and split repository into subtrees
+
+
+SYNOPSIS
+--------
+[verse]
+'git subtree' add   -P <prefix> <commit>
+'git subtree' pull  -P <prefix> <repository> <refspec...>
+'git subtree' push  -P <prefix> <repository> <refspec...>
+'git subtree' merge -P <prefix> <commit>
+'git subtree' split -P <prefix> [OPTIONS] [<commit>]
+
+
+DESCRIPTION
+-----------
+Subtrees allow subprojects to be included within a subdirectory
+of the main project, optionally including the subproject's
+entire history.
+
+For example, you could include the source code for a library
+as a subdirectory of your application.
+
+Subtrees are not to be confused with submodules, which are meant for
+the same task. Unlike submodules, subtrees do not need any special
+constructions (like .gitmodule files or gitlinks) be present in
+your repository, and do not force end-users of your
+repository to do anything special or to understand how subtrees
+work. A subtree is just a subdirectory that can be
+committed to, branched, and merged along with your project in
+any way you want.
+
+They are also not to be confused with using the subtree merge
+strategy. The main difference is that, besides merging
+the other project as a subdirectory, you can also extract the
+entire history of a subdirectory from your project and make it
+into a standalone project. Unlike the subtree merge strategy
+you can alternate back and forth between these
+two operations. If the standalone library gets updated, you can
+automatically merge the changes into your project; if you
+update the library inside your project, you can "split" the
+changes back out again and merge them back into the library
+project.
+
+For example, if a library you made for one application ends up being
+useful elsewhere, you can extract its entire history and publish
+that as its own git repository, without accidentally
+intermingling the history of your application project.
+
+[TIP]
+In order to keep your commit messages clean, we recommend that
+people split their commits between the subtrees and the main
+project as much as possible.  That is, if you make a change that
+affects both the library and the main application, commit it in
+two pieces.  That way, when you split the library commits out
+later, their descriptions will still make sense.  But if this
+isn't important to you, it's not *necessary*.  git subtree will
+simply leave out the non-library-related parts of the commit
+when it splits it out into the subproject later.
+
+
+COMMANDS
+--------
+add::
+	Create the <prefix> subtree by importing its contents
+	from the given <refspec> or <repository> and remote <refspec>.
+	A new commit is created	automatically, joining the imported
+	project's history with your own.  With '--squash', imports
+	only a single commit from the subproject, rather than its
+	entire history.
+
+merge::
+	Merge recent changes up to <commit> into the <prefix>
+	subtree.  As with normal 'git merge', this doesn't
+	remove your own local changes; it just merges those
+	changes into the latest <commit>.  With '--squash',
+	creates only one commit that contains all the changes,
+	rather than merging in the entire history.
+
+	If you use '--squash', the merge direction doesn't
+	always have to be forward; you can use this command to
+	go back in time from v2.5 to v2.4, for example.  If your
+	merge introduces a conflict, you can resolve it in the
+	usual ways.
+	
+pull::
+	Exactly like 'merge', but parallels 'git pull' in that
+	it fetches the given commit from the specified remote
+	repository.
+	
+push::
+	Does a 'split' (see above) using the <prefix> supplied
+	and then does a 'git push' to push the result to the 
+	repository and refspec. This can be used to push your
+	subtree to different branches of the remote repository.
+
+split::
+	Extract a new, synthetic project history from the
+	history of the <prefix> subtree.  The new history
+	includes only the commits (including merges) that
+	affected <prefix>, and each of those commits now has the
+	contents of <prefix> at the root of the project instead
+	of in a subdirectory.  Thus, the newly created history
+	is suitable for export as a separate git repository.
+	
+	After splitting successfully, a single commit id is
+	printed to stdout.  This corresponds to the HEAD of the
+	newly created tree, which you can manipulate however you
+	want.
+	
+	Repeated splits of exactly the same history are
+	guaranteed to be identical (ie. to produce the same
+	commit ids).  Because of this, if you add new commits
+	and then re-split, the new commits will be attached as
+	commits on top of the history you generated last time,
+	so 'git merge' and friends will work as expected.
+	
+	Note that if you use '--squash' when you merge, you
+	should usually not just '--rejoin' when you split.
+
+
+OPTIONS
+-------
+-q::
+--quiet::
+	Suppress unnecessary output messages on stderr.
+
+-d::
+--debug::
+	Produce even more unnecessary output messages on stderr.
+
+-P <prefix>::
+--prefix=<prefix>::
+	Specify the path in the repository to the subtree you
+	want to manipulate.  This option is mandatory
+	for all commands.
+
+-m <message>::
+--message=<message>::
+	This option is only valid for add, merge and pull (unsure).
+	Specify <message> as the commit message for the merge commit.
+
+
+OPTIONS FOR add, merge, push, pull
+----------------------------------
+--squash::
+	This option is only valid for add, merge, push and pull
+	commands.
+
+	Instead of merging the entire history from the subtree
+	project, produce only a single commit that contains all
+	the differences you want to merge, and then merge that
+	new commit into your project.
+	
+	Using this option helps to reduce log clutter. People
+	rarely want to see every change that happened between
+	v1.0 and v1.1 of the library they're using, since none of the
+	interim versions were ever included in their application.
+	
+	Using '--squash' also helps avoid problems when the same
+	subproject is included multiple times in the same
+	project, or is removed and then re-added.  In such a
+	case, it doesn't make sense to combine the histories
+	anyway, since it's unclear which part of the history
+	belongs to which subtree.
+	
+	Furthermore, with '--squash', you can switch back and
+	forth between different versions of a subtree, rather
+	than strictly forward.  'git subtree merge --squash'
+	always adjusts the subtree to match the exactly
+	specified commit, even if getting to that commit would
+	require undoing some changes that were added earlier.
+	
+	Whether or not you use '--squash', changes made in your
+	local repository remain intact and can be later split
+	and send upstream to the subproject.
+
+
+OPTIONS FOR split
+-----------------
+--annotate=<annotation>::
+	This option is only valid for the split command.
+
+	When generating synthetic history, add <annotation> as a
+	prefix to each commit message.  Since we're creating new
+	commits with the same commit message, but possibly
+	different content, from the original commits, this can help
+	to differentiate them and avoid confusion.
+	
+	Whenever you split, you need to use the same
+	<annotation>, or else you don't have a guarantee that
+	the new re-created history will be identical to the old
+	one.  That will prevent merging from working correctly. 
+	git subtree tries to make it work anyway, particularly
+	if you use --rejoin, but it may not always be effective.
+
+-b <branch>::
+--branch=<branch>::
+	This option is only valid for the split command.
+
+	After generating the synthetic history, create a new
+	branch called <branch> that contains the new history. 
+	This is suitable for immediate pushing upstream. 
+	<branch> must not already exist.
+
+--ignore-joins::
+	This option is only valid for the split command.
+
+	If you use '--rejoin', git subtree attempts to optimize
+	its history reconstruction to generate only the new
+	commits since the last '--rejoin'.  '--ignore-join'
+	disables this behaviour, forcing it to regenerate the
+	entire history.  In a large project, this can take a
+	long time.
+
+--onto=<onto>::
+	This option is only valid for the split command.
+
+	If your subtree was originally imported using something
+	other than git subtree, its history may not match what
+	git subtree is expecting.  In that case, you can specify
+	the commit id <onto> that corresponds to the first
+	revision of the subproject's history that was imported
+	into your project, and git subtree will attempt to build
+	its history from there.
+	
+	If you used 'git subtree add', you should never need
+	this option.
+
+--rejoin::
+	This option is only valid for the split command.
+
+	After splitting, merge the newly created synthetic
+	history back into your main project.  That way, future
+	splits can search only the part of history that has
+	been added since the most recent --rejoin.
+	
+	If your split commits end up merged into the upstream
+	subproject, and then you want to get the latest upstream
+	version, this will allow git's merge algorithm to more
+	intelligently avoid conflicts (since it knows these
+	synthetic commits are already part of the upstream
+	repository).
+	
+	Unfortunately, using this option results in 'git log'
+	showing an extra copy of every new commit that was
+	created (the original, and the synthetic one).
+	
+	If you do all your merges with '--squash', don't use
+	'--rejoin' when you split, because you don't want the
+	subproject's history to be part of your project anyway.
+
+
+EXAMPLE 1. Add command
+----------------------
+Let's assume that you have a local repository that you would like
+to add an external vendor library to. In this case we will add the
+git-subtree repository as a subdirectory of your already existing
+git-extensions repository in ~/git-extensions/:
+
+	$ git subtree add --prefix=git-subtree --squash \
+		git://github.com/apenwarr/git-subtree.git master
+
+'master' needs to be a valid remote ref and can be a different branch
+name
+
+You can omit the --squash flag, but doing so will increase the number
+of commits that are incldued in your local repository.
+
+We now have a ~/git-extensions/git-subtree directory containing code
+from the master branch of git://github.com/apenwarr/git-subtree.git
+in our git-extensions repository.
+
+EXAMPLE 2. Extract a subtree using commit, merge and pull
+---------------------------------------------------------
+Let's use the repository for the git source code as an example.
+First, get your own copy of the git.git repository:
+
+	$ git clone git://git.kernel.org/pub/scm/git/git.git test-git
+	$ cd test-git
+
+gitweb (commit 1130ef3) was merged into git as of commit
+0a8f4f0, after which it was no longer maintained separately. 
+But imagine it had been maintained separately, and we wanted to
+extract git's changes to gitweb since that time, to share with
+the upstream.  You could do this:
+
+	$ git subtree split --prefix=gitweb --annotate='(split) ' \
+        	0a8f4f0^.. --onto=1130ef3 --rejoin \
+        	--branch gitweb-latest
+        $ gitk gitweb-latest
+        $ git push git@github.com:whatever/gitweb.git gitweb-latest:master
+        
+(We use '0a8f4f0^..' because that means "all the changes from
+0a8f4f0 to the current version, including 0a8f4f0 itself.")
+
+If gitweb had originally been merged using 'git subtree add' (or
+a previous split had already been done with --rejoin specified)
+then you can do all your splits without having to remember any
+weird commit ids:
+
+	$ git subtree split --prefix=gitweb --annotate='(split) ' --rejoin \
+		--branch gitweb-latest2
+
+And you can merge changes back in from the upstream project just
+as easily:
+
+	$ git subtree pull --prefix=gitweb \
+		git@github.com:whatever/gitweb.git master
+
+Or, using '--squash', you can actually rewind to an earlier
+version of gitweb:
+
+	$ git subtree merge --prefix=gitweb --squash gitweb-latest~10
+
+Then make some changes:
+
+	$ date >gitweb/myfile
+	$ git add gitweb/myfile
+	$ git commit -m 'created myfile'
+
+And fast forward again:
+
+	$ git subtree merge --prefix=gitweb --squash gitweb-latest
+
+And notice that your change is still intact:
+	
+	$ ls -l gitweb/myfile
+
+And you can split it out and look at your changes versus
+the standard gitweb:
+
+	git log gitweb-latest..$(git subtree split --prefix=gitweb)
+
+EXAMPLE 3. Extract a subtree using branch
+-----------------------------------------
+Suppose you have a source directory with many files and
+subdirectories, and you want to extract the lib directory to its own
+git project. Here's a short way to do it:
+
+First, make the new repository wherever you want:
+
+	$ <go to the new location>
+	$ git init --bare
+
+Back in your original directory:
+
+	$ git subtree split --prefix=lib --annotate="(split)" -b split
+
+Then push the new branch onto the new empty repository:
+
+	$ git push <new-repo> split:master

+	   This trick arranges for messages to be emitted in the user's
+	   requested encoding, but avoids setting LC_CTYPE from the
+	   environment for the whole program.
+
+	   This primarily done to avoid a bug in vsnprintf in the GNU C
+	   Library [1]. which triggered a "your vsnprintf is broken" error
+	   on Git's own repository when inspecting v0.99.6~1 under a UTF-8
+	   locale.
+
+	   That commit contains a ISO-8859-1 encoded author name, which
+	   the locale aware vsnprintf(3) won't interpolate in the format
+	   argument, due to mismatch between the data encoding and the
+	   locale.
+
+	   Even if it wasn't for that bug we wouldn't want to use LC_CTYPE at
+	   this point, because it'd require auditing all the code that uses C
+	   functions whose semantics are modified by LC_CTYPE.
+
+	   But only setting LC_MESSAGES as we do creates a problem, since
+	   we declare the encoding of our PO files[2] the gettext
+	   implementation will try to recode it to the user's locale, but
+	   without LC_CTYPE it'll emit something like this on 'git init'
+	   under the Icelandic locale:
+
+	       Bj? til t?ma Git lind ? /hlagh/.git/
+
+	   Gettext knows about the encoding of our PO file, but we haven't
+	   told it about the user's encoding, so all the non-US-ASCII
+	   characters get encoded to question marks.
+
+	   But we're in luck! We can set LC_CTYPE from the environment
+	   only while we call nl_langinfo and
+	   bind_textdomain_codeset. That suffices to tell gettext what
+	   encoding it should emit in, so it'll now say:
+
+	       Bjó til tóma Git lind í /hlagh/.git/
+
+	   And the equivalent ISO-8859-1 string will be emitted under a
+	   ISO-8859-1 locale.
+
+	   With this change way we get the advantages of setting LC_CTYPE
+	   (talk to the user in his language/encoding), without the major
+	   drawbacks (changed semantics for C functions we rely on).
+
+	   However foreign functions using other message catalogs that
+	   aren't using our neat trick will still have a problem, e.g. if
+	   we have to call perror(3):
+
+	   #include <stdio.h>
+	   #include <locale.h>
+	   #include <errno.h>
+
+	   int main(void)
+	   {
+		   setlocale(LC_MESSAGES, "");
+		   setlocale(LC_CTYPE, "C");
+		   errno = ENODEV;
+		   perror("test");
+		   return 0;
+	   }
+
+	   Running that will give you a message with question marks:
+
+	   $ LANGUAGE= LANG=de_DE.utf8 ./test
+	   test: Kein passendes Ger?t gefunden
+
+	   In the long term we should probably see about getting that
+	   vsnprintf bug in glibc fixed, and audit our code so it won't
+	   fall apart under a non-C locale.
+
+	   Then we could simply set LC_CTYPE from the environment, which would
+	   make things like the external perror(3) messages work.
+
+	   See t/t0203-gettext-setlocale-sanity.sh's "gettext.c" tests for
+	   regression tests.
+
+	   1. http://sourceware.org/bugzilla/show_bug.cgi?id=6530

 Gitweb repositories
 -------------------
 
-- By default all git repositories under projectroot are visible and
-  available to gitweb. The list of projects is generated by default by
-  scanning the projectroot directory for git repositories (for object
-  databases to be more exact).
-
-  You can provide a pre-generated list of [visible] repositories,
-  together with information about their owners (the project ownership
-  defaults to the owner of the repository directory otherwise), by setting
-  the GITWEB_LIST build configuration variable (or the $projects_list
-  variable in the gitweb config file) to point to a plain file.
-
-  Each line of the projects list file should consist of the url-encoded path
-  to the project repository database (relative to projectroot), followed
-  by the url-encoded project owner on the same line (separated by a space).
-  Spaces in both project path and project owner have to be encoded as either
-  '%20' or '+'.
-
-  Other characters that have to be url-encoded, i.e. replaced by '%'
-  followed by two-digit character number in octal, are: other whitespace
-  characters (because they are field separator in a record), plus sign '+'
-  (because it can be used as replacement for spaces), and percent sign '%'
-  (which is used for encoding / escaping).
-
-  You can generate the projects list index file using the project_index
-  action (the 'TXT' link on projects list page) directly from gitweb.
-
-- By default, even if a project is not visible on projects list page, you
-  can view it nevertheless by hand-crafting a gitweb URL. You can set the
-  GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export
-  variable in the gitweb config file) to only allow viewing of
-  repositories also shown on the overview page.
-
-- Alternatively, you can configure gitweb to only list and allow
-  viewing of the explicitly exported repositories, via the
-  GITWEB_EXPORT_OK build configuration variable (or the $export_ok
-  variable in gitweb config file). If it evaluates to true, gitweb
-  shows repositories only if this file exists in its object database
-  (if directory has the magic file named $export_ok).
-
-- Finally, it is possible to specify an arbitrary perl subroutine that
-  will be called for each project to determine if it can be exported.
-  The subroutine receives an absolute path to the project as its only
-  parameter.
-
-  For example, if you use mod_perl to run the script, and have dumb
-  http protocol authentication configured for your repositories, you
-  can use the following hook to allow access only if the user is
-  authorized to read the files:
-
-    $export_auth_hook = sub {
-        use Apache2::SubRequest ();
-        use Apache2::Const -compile => qw(HTTP_OK);
-        my $path = "$_[0]/HEAD";
-        my $r    = Apache2::RequestUtil->request;
-        my $sub  = $r->lookup_file($path);
-        return $sub->filename eq $path

-Gitweb config file variables
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can set, among others, the following variables in gitweb config files
-(with the exception of $projectroot and $projects_list this list does
-not include variables usually directly set during build):
- * $GIT
-   Core git executable to use.  By default set to "$GIT_BINDIR/git", which
-   in turn is by default set to "$(bindir)/git".  If you use git from binary
-   package, set this to "/usr/bin/git".  This can just be "git" if your
-   webserver has a sensible PATH.  If you have multiple git versions
-   installed it can be used to choose which one to use.
- * $version
-   Gitweb version, set automatically when creating gitweb.cgi from
-   gitweb.perl. You might want to modify it if you are running modified
-   gitweb.
- * $projectroot
-   Absolute filesystem path which will be prepended to project path;
-   the path to repository is $projectroot/$project.  Set to
-   $GITWEB_PROJECTROOT during installation.  This variable have to be
-   set correctly for gitweb to find repositories.
- * $projects_list
-   Source of projects list, either directory to scan, or text file
-   with list of repositories (in the "<URI-encoded repository path> SP
-   <URI-encoded repository owner>" line format; actually there can be
-   any sequence of whitespace in place of space (SP)).  Set to
-   $GITWEB_LIST during installation.  If empty, $projectroot is used
-   to scan for repositories.
- * $my_url, $my_uri
-   Full URL and absolute URL of gitweb script;
-   in earlier versions of gitweb you might have need to set those
-   variables, now there should be no need to do it.  See
-   $per_request_config if you need to set them still.
- * $base_url
-   Base URL for relative URLs in pages generated by gitweb,
-   (e.g. $logo, $favicon, @stylesheets if they are relative URLs),
-   needed and used only for URLs with nonempty PATH_INFO via
-   <base href="$base_url">.  Usually gitweb sets its value correctly,
-   and there is no need to set this variable, e.g. to $my_uri or "/".
-   See $per_request_config if you need to set it anyway.
- * $home_link
-   Target of the home link on top of all pages (the first part of view
-   "breadcrumbs").  By default set to absolute URI of a page ($my_uri).
- * @stylesheets
-   List of URIs of stylesheets (relative to base URI of a page). You
-   might specify more than one stylesheet, for example use gitweb.css
-   as base, with site specific modifications in separate stylesheet
-   to make it easier to upgrade gitweb. You can add 'site' stylesheet
-   for example by using
-      push @stylesheets, "gitweb-site.css";
-   in the gitweb config file.
- * $logo_url, $logo_label
-   URI and label (title) of GIT logo link (or your site logo, if you choose
-   to use different logo image). By default they point to git homepage;
-   in the past they pointed to git documentation at www.kernel.org.
- * $projects_list_description_width
-   The width (in characters) of the projects list "Description" column.
-   Longer descriptions will be cut (trying to cut at word boundary);
-   full description is available as 'title' attribute (usually shown on
-   mouseover).  By default set to 25, which might be too small if you
-   use long project descriptions.
- * $projects_list_group_categories
-   Enables the grouping of projects by category on the project list page.
-   The category of a project is determined by the $GIT_DIR/category
-   file or the 'gitweb.category' variable in its repository configuration.
-   Disabled by default.
- * $project_list_default_category
-   Default category for projects for which none is specified.  If set
-   to the empty string, such projects will remain uncategorized and
-   listed at the top, above categorized projects.
- * @git_base_url_list
-   List of git base URLs used for URL to where fetch project from, shown
-   in project summary page.  Full URL is "$git_base_url/$project".
-   You can setup multiple base URLs (for example one for  git:// protocol
-   access, and one for http:// "dumb" protocol access).  Note that per
-   repository configuration in 'cloneurl' file, or as values of gitweb.url
-   project config.
- * $default_blob_plain_mimetype
-   Default mimetype for blob_plain (raw) view, if mimetype checking
-   doesn't result in some other type; by default 'text/plain'.
- * $default_text_plain_charset
-   Default charset for text files. If not set, web server configuration
-   would be used.
- * $mimetypes_file
-   File to use for (filename extension based) guessing of MIME types before
-   trying /etc/mime.types. Path, if relative, is taken currently as
-   relative to the current git repository.
- * $fallback_encoding
-   Gitweb assumes this charset if line contains non-UTF-8 characters.
-   Fallback decoding is used without error checking, so it can be even
-   'utf-8'. Value must be valid encoding; see Encoding::Supported(3pm) man
-   page for a list.   By default 'latin1', aka. 'iso-8859-1'.
- * @diff_opts
-   Rename detection options for git-diff and git-diff-tree. By default
-   ('-M'); set it to ('-C') or ('-C', '-C') to also detect copies, or
-   set it to () if you don't want to have renames detection.
- * $prevent_xss
-   If true, some gitweb features are disabled to prevent content in
-   repositories from launching cross-site scripting (XSS) attacks.  Set this
-   to true if you don't trust the content of your repositories. The default
-   is false.
- * $maxload
-   Used to set the maximum load that we will still respond to gitweb queries.
-   If server load exceed this value then return "503 Service Unavailable" error.
-   Server load is taken to be 0 if gitweb cannot determine its value.  Set it to
-   undefined value to turn it off.  The default is 300.
- * $highlight_bin
-   Path to the highlight executable to use (must be the one from
-   http://www.andre-simon.de due to assumptions about parameters and output).
-   Useful if highlight is not installed on your webserver's PATH.
-   [Default: highlight]
- * $per_request_config
-   If set to code reference, it would be run once per each request.  You can
-   set parts of configuration that change per session, e.g. by setting it to
-     sub { $ENV{GL_USER} = $cgi->remote_user || "gitweb"; }
-   Otherwise it is treated as boolean value: if true gitweb would process
-   config file once per request, if false it would process config file only
-   once.  Note: $my_url, $my_uri, and $base_url are overwritten with
-   their default values before every request, so if you want to change
-   them, be sure to set this variable to true or a code reference effecting
-   the desired changes.  The default is true.
-
-Projects list file format
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Instead of having gitweb find repositories by scanning filesystem starting
-from $projectroot (or $projects_list, if it points to directory), you can
-provide list of projects by setting $projects_list to a text file with list
-of projects (and some additional info).  This file uses the following
-format:
-
-One record (for project / repository) per line, whitespace separated fields;
-does not support (at least for now) lines continuation (newline escaping).
-Leading and trailing whitespace are ignored, any run of whitespace can be
-used as field separator (rules for Perl's "split(' ', $line)").  Keyed by
-the first field, which is project name, i.e. path to repository GIT_DIR
-relative to $projectroot.  Fields use modified URI encoding, defined in
-RFC 3986, section 2.1 (Percent-Encoding), or rather "Query string encoding"
-(see http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference
-being that SP (' ') can be encoded as '+' (and therefore '+' has to be also
-percent-encoded).  Reserved characters are: '%' (used for encoding), '+'
-(can be used to encode SPACE), all whitespace characters as defined in Perl,
-including SP, TAB and LF, (used to separate fields in a record).
-
-Currently list of fields is
- * <repository path>  - path to repository GIT_DIR, relative to $projectroot
- * <repository owner> - displayed as repository owner, preferably full name,
-                        or email, or both
-
-You can additionally use $projects_list file to limit which repositories
-are visible, and together with $strict_export to limit access to
-repositories (see "Gitweb repositories" section in gitweb/INSTALL).
-
-
-Per-repository gitweb configuration
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You can also configure individual repositories shown in gitweb by creating
-file in the GIT_DIR of git repository, or by setting some repo configuration
-variable (in GIT_DIR/config).
-
-You can use the following files in repository:
- * README.html
-   A .html file (HTML fragment) which is included on the gitweb project
-   summary page inside <div> block element. You can use it for longer
-   description of a project, to provide links (for example to project's
-   homepage), etc. This is recognized only if XSS prevention is off
-   ($prevent_xss is false); a way to include a readme safely when XSS
-   prevention is on may be worked out in the future.
- * description (or gitweb.description)
-   Short (shortened by default to 25 characters in the projects list page)
-   single line description of a project (of a repository). Plain text file;
-   HTML will be escaped. By default set to
-     Unnamed repository; edit this file to name it for gitweb.
-   from the template during repository creation. You can use the
-   gitweb.description repo configuration variable, but the file takes
-   precedence.
- * category (or gitweb.category)
-   Singe line category of a project, used to group projects if
-   $projects_list_group_categories is enabled. By default (file and
-   configuration variable absent), uncategorized projects are put in
-   the $project_list_default_category category. You can use the
-   gitweb.category repo configuration variable, but the file takes
-   precedence.
- * cloneurl (or multiple-valued gitweb.url)
-   File with repository URL (used for clone and fetch), one per line.
-   Displayed in the project summary page. You can use multiple-valued
-   gitweb.url repository configuration variable for that, but the file
-   takes precedence.
- * gitweb.owner
-   You can use the gitweb.owner repository configuration variable to set
-   repository's owner. It is displayed in the project list and summary
-   page. If it's not set, filesystem directory's owner is used
-   (via GECOS field / real name field from getpwiud(3)).
- * various gitweb.* config variables (in config)
-   Read description of %feature hash for detailed list, and some
-   descriptions.
-
-
-Webserver configuration
------------------------
-
-If you want to have one URL for both gitweb and your http://
-repositories, you can configure apache like this:
-
-<VirtualHost *:80>
-    ServerName		git.example.org
-    DocumentRoot	/pub/git
-    SetEnv			GITWEB_CONFIG	/etc/gitweb.conf
-
-    # turning on mod rewrite
-    RewriteEngine on
-
-    # make the front page an internal rewrite to the gitweb script
-    RewriteRule ^/$  /cgi-bin/gitweb.cgi
-
-    # make access for "dumb clients" work
-    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ /cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
-</VirtualHost>
-
-The above configuration expects your public repositories to live under
-/pub/git and will serve them as http://git.domain.org/dir-under-pub-git,
-both as cloneable GIT URL and as browseable gitweb interface.
-If you then start your git-daemon with --base-path=/pub/git --export-all
-then you can even use the git:// URL with exactly the same path.
-
-Setting the environment variable GITWEB_CONFIG will tell gitweb to use
-the named file (i.e. in this example /etc/gitweb.conf) as a
-configuration for gitweb.  Perl variables defined in here will
-override the defaults given at the head of the gitweb.perl (or
-gitweb.cgi).  Look at the comments in that file for information on
-which variables and what they mean.
-
-If you use the rewrite rules from the example you'll likely also need
-something like the following in your gitweb.conf (or gitweb_config.perl) file:
-
-  @stylesheets = ("/some/absolute/path/gitweb.css");
-  $my_uri = "/";
-  $home_link = "/";
-
-
-Webserver configuration with multiple projects' root
-----------------------------------------------------
-
-If you want to use gitweb with several project roots you can edit your apache
-virtual host and gitweb.conf configuration files like this :
-
-virtual host configuration :
-
-<VirtualHost *:80>
-    ServerName			git.example.org
-    DocumentRoot		/pub/git
-    SetEnv				GITWEB_CONFIG	/etc/gitweb.conf
-
-    # turning on mod rewrite
-    RewriteEngine on
-
-    # make the front page an internal rewrite to the gitweb script
-    RewriteRule ^/$ 		/cgi-bin/gitweb.cgi [QSA,L,PT]
-
-    # look for a public_git folder in unix users' home
-    # http://git.example.org/~<user>/
-    RewriteRule ^/\~([^\/]+)(/|/gitweb.cgi)?$	/cgi-bin/gitweb.cgi [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
-
-    # http://git.example.org/+<user>/
-    #RewriteRule ^/\+([^\/]+)(/|/gitweb.cgi)?$	/cgi-bin/gitweb.cgi [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
-
-    # http://git.example.org/user/<user>/
-    #RewriteRule ^/user/([^\/]+)/(gitweb.cgi)?$	/cgi-bin/gitweb.cgi [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT]
-
-    # defined list of project roots
-    RewriteRule ^/scm(/|/gitweb.cgi)?$		/cgi-bin/gitweb.cgi [QSA,E=GITWEB_PROJECTROOT:/pub/scm/,L,PT]
-    RewriteRule ^/var(/|/gitweb.cgi)?$		/cgi-bin/gitweb.cgi [QSA,E=GITWEB_PROJECTROOT:/var/git/,L,PT]
-
-    # make access for "dumb clients" work
-    RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ /cgi-bin/gitweb.cgi%{REQUEST_URI}  [L,PT]
-</VirtualHost>
-
-gitweb.conf configuration :
-
-$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git";
-
-These configurations enable two things. First, each unix user (<user>) of the
-server will be able to browse through gitweb git repositories found in
-~/public_git/ with the following url : http://git.example.org/~<user>/
-
-If you do not want this feature on your server just remove the second rewrite rule.
-
-If you already use mod_userdir in your virtual host or you don't want to use
-the '~' as first character just comment or remove the second rewrite rule and
-uncomment one of the following according to what you want.
-
-Second, repositories found in /pub/scm/ and /var/git/ will be accesible
-through http://git.example.org/scm/ and http://git.example.org/var/.
-You can add as many project roots as you want by adding rewrite rules like the
-third and the fourth.
-
-
-PATH_INFO usage
------------------------
-If you enable PATH_INFO usage in gitweb by putting
-
-   $feature{'pathinfo'}{'default'} = [1];
-
-in your gitweb.conf, it is possible to set up your server so that it
-consumes and produces URLs in the form
-
-http://git.example.com/project.git/shortlog/sometag
-
-by using a configuration such as the following, that assumes that
-/var/www/gitweb is the DocumentRoot of your webserver, and that it
-contains the gitweb.cgi script and complementary static files
-(stylesheet, favicon):
-
-<VirtualHost *:80>
-	ServerAlias git.example.com
-
-	DocumentRoot /var/www/gitweb
-
-	<Directory /var/www/gitweb>
-		Options ExecCGI
-		AddHandler cgi-script cgi
-
-		DirectoryIndex gitweb.cgi
-
-		RewriteEngine On
-		RewriteCond %{REQUEST_FILENAME} !-f
-		RewriteCond %{REQUEST_FILENAME} !-d
-		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
-	</Directory>
-</VirtualHost>
-
-The rewrite rule guarantees that existing static files will be properly
-served, whereas any other URL will be passed to gitweb as PATH_INFO
-parameter.
-
-Notice that in this case you don't need special settings for
-@stylesheets, $my_uri and $home_link, but you lose "dumb client" access
-to your project .git dirs. A possible workaround for the latter is the
-following: in your project root dir (e.g. /pub/git) have the projects
-named without a .git extension (e.g. /pub/git/project instead of
-/pub/git/project.git) and configure Apache as follows:
-
-<VirtualHost *:80>
-	ServerAlias git.example.com
-
-	DocumentRoot /var/www/gitweb
-
-	AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3
-	<Directory /var/www/gitweb>
-		Options ExecCGI
-		AddHandler cgi-script cgi
-
-		DirectoryIndex gitweb.cgi
-
-		RewriteEngine On
-		RewriteCond %{REQUEST_FILENAME} !-f
-		RewriteCond %{REQUEST_FILENAME} !-d
-		RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
-	</Directory>
-</VirtualHost>
-
-The additional AliasMatch makes it so that
-
-http://git.example.com/project.git
-
-will give raw access to the project's git dir (so that the project can
-be cloned), while
-
-http://git.example.com/project
-
-will provide human-friendly gitweb access.
-
-This solution is not 100% bulletproof, in the sense that if some project
-has a named ref (branch, tag) starting with 'git/', then paths such as
+See also gitweb.conf(5) manpage.
 
-http://git.example.com/project/command/abranch..git/abranch
 
-will fail with a 404 error.
+Web server configuration
+------------------------
+Gitweb can be run as CGI script, as legacy mod_perl application (using
+ModPerl::Registry), and as FastCGI script.  You can find some simple examples
+in "Example web server configuration" section in INSTALL file for gitweb (in
+gitweb/INSTALL).
 
+See "Webserver configuration" and "Advanced web server setup" sections in
+gitweb(1) manpage.

+
+Git's internal Perl interface to gettext via L<Locale::Messages>. If
+L<Locale::Messages> can't be loaded (it's not a core module) we
+provide stub passthrough fallbacks.
+
+This is a distilled interface to gettext, see C<info '(gettext)Perl'>
+for the full interface. This module implements only a small part of
+it.
+
+=head1 FUNCTIONS
+
+=head2 __($)
+
+L<Locale::Messages>'s gettext function if all goes well, otherwise our
+passthrough fallback function.

+
+	my $ra = Git::SVN::Ra->new($url);
+	my %opts = (
+		r => 19,

+
+=head1 DESCRIPTION
+
+This module is an implementation detail of the "git svn" command.
+Do not use it unless you are developing git-svn.
+
+This module adapts the C<SVN::Delta::Editor> object returned by
+C<SVN::Delta::get_commit_editor> and drives it to convey the
+difference between two git tree objects to a remote Subversion
+repository.
+
+The interface will change as git-svn evolves.
+
+=head1 DEPENDENCIES
+
+Subversion perl bindings,
+the core L<Carp> and L<IO::File> modules,
+and git's L<Git> helper module.
+
+C<Git::SVN::Editor> has not been tested using callers other than
+B<git-svn> itself.
+
+=head1 SEE ALSO
+
+L<SVN::Delta>,
+L<Git::SVN::Fetcher>.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+None.

+
+This is a subclass of C<SVN::Delta::Editor>, which means it implements
+callbacks to act as a consumer of Subversion tree deltas.  This
+particular implementation of those callbacks is meant to store
+information about the resulting content which B<git svn fetch> could
+use to populate new commits and new entries for F<unhandled.log>.
+More specifically:
+
+=over
+
+=item * Additions, removals, and modifications of files are propagated
+to git-svn's index file F<$GIT_DIR/svn/$refname/index> using
+B<git update-index>.
+
+=item * Changes in Subversion path properties are recorded in the
+C<dir_prop> and C<file_prop> fields (which are hashes).
+
+=item * Addition and removal of empty directories are indicated by
+entries with value 1 and 0 respectively in the C<empty> hash.
+
+=item * Paths that are present but cannot be conveyed (presumably due
+to permissions) are recorded in the C<absent_file> and
+C<absent_dirs> hashes.  For each key, the corresponding value is
+a list of paths under that directory that were present but
+could not be conveyed.

+=head1 NAME
+
+Git::SVN::Memoize::YAML - store Memoized data in YAML format
+
+=head1 SYNOPSIS
+
+    use Memoize;
+    use Git::SVN::Memoize::YAML;
+
+    tie my %cache => 'Git::SVN::Memoize::YAML', $filename;
+    memoize('slow_function', SCALAR_CACHE => [HASH => \%cache]);
+    slow_function(arguments);
+
+=head1 DESCRIPTION
+
+This module provides a class that can be used to tie a hash to a
+YAML file.  The file is read when the hash is initialized and
+rewritten when the hash is destroyed.
+
+The intent is to allow L<Memoize> to back its cache with a file in
+YAML format, just like L<Memoize::Storable> allows L<Memoize> to
+back its cache with a file in Storable format.  Unlike the Storable
+format, the YAML format is platform-independent and fairly stable.
+
+Carps on error.
+
+=head1 DIAGNOSTICS
+
+See L<YAML::Any>.
+
+=head1 DEPENDENCIES
+
+L<YAML::Any> from CPAN.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+The entire cache is read into a Perl hash when loading the file,
+so this is not very scalable.

+=head1 DESCRIPTION
+
+This module is an implementation detail of the "git svn" command.
+It implements git-svn's authentication policy.  Do not use it unless
+you are developing git-svn.
+
+The interface will change as git-svn evolves.

+Git::SVN::Ra - Subversion remote access functions for git-svn
+
+=head1 SYNOPSIS
+
+    use Git::SVN::Ra;
+
+    my $ra = Git::SVN::Ra->new($branchurl);
+    my ($dirents, $fetched_revnum, $props) =
+        $ra->get_dir('.', $SVN::Core::INVALID_REVNUM);
+
+=head1 DESCRIPTION
+
+This is a wrapper around the L<SVN::Ra> module for use by B<git-svn>.
+It fills in some default parameters (such as the authentication
+scheme), smooths over incompatibilities between libsvn versions, adds
+caching, and implements some functions specific to B<git-svn>.
+
+Do not use it unless you are developing git-svn.  The interface will
+change as git-svn evolves.
+
+=head1 DEPENDENCIES
+
+Subversion perl bindings,
+L<Git::SVN>.
+
+C<Git::SVN::Ra> has not been tested using callers other than
+B<git-svn> itself.
+
+=head1 SEE ALSO
+
+L<SVN::Ra>.
+
+=head1 INCOMPATIBILITIES
+
+None reported.
+
+=head1 BUGS
+
+None.

+Core GIT Translations
+=====================
+
+This directory holds the translations for the core of Git. This document
+describes how you can contribute to the effort of enhancing the language
+coverage and maintaining the translation.
+
+The localization (l10n) coordinator, Jiang Xin <worldhello.net@gmail.com>,
+coordinates our localization effort in the l10 coordinator repository:
+
+        https://github.com/git-l10n/git-po/
+
+As a contributor for a language XX, you should first check TEAMS file in
+this directory to see whether a dedicated repository for your language XX
+exists. Fork the dedicated repository and start to work if it exists.
+
+If you are the first contributor for the language XX, please fork this
+repository, prepare and/or update the translated message file po/XX.po
+(described later), and ask the l10n coordinator to pull your work.
+
+If there are multiple contributors for the same language, please first
+coordinate among yourselves and nominate the team leader for your
+language, so that the l10n coordinator only needs to interact with one
+person per language.
+
+The overall data-flow looks like this:
+
+    +-------------------+            +------------------+
+    | Git source code   | ---(1)---> | L10n coordinator |
+    | repository        | <---(4)--- | repository       |
+    +-------------------+            +------------------+
+                                          |      ^
+                                         (2)    (3)
+                                          V      |

+                                     | Language Team XX |
+                                     +------------------+
+
+ * Translatable strings are marked in the source file.
+ * L10n coordinator pulls from the source (1)
+ * L10n coordinator updates the message template po/git.pot
+ * Language team pulls from L10n coordinator (2)
+ * Language team updates the message file po/XX.po
+ * L10n coordinator pulls from Language team (3)
+ * L10n coordinator asks the result to be pulled (4).
+
+
+Maintaining the po/git.pot file
+-------------------------------
+
+(This is done by the l10n coordinator).
+
+The po/git.pot file contains a message catalog extracted from Git's
+sources. The l10n coordinator maintains it by adding new translations with
+msginit(1), or update existing ones with msgmerge(1).  In order to update
+the Git sources to extract the messages from, the l10n coordinator is
+expected to pull from the main git repository at strategic point in
+history (e.g. when a major release and release candidates are tagged),
+and then run "make pot" at the top-level directory.
+
+Language contributors use this file to prepare translations for their
+language, but they are not expected to modify it.
+
+
+Initializing a XX.po file
+-------------------------
+
+(This is done by the language teams).
+
+If your language XX does not have translated message file po/XX.po yet,
+you add a translation for the first time by running:
+
+    msginit --locale=XX
+
+in the po/ directory, where XX is the locale, e.g. "de", "is", "pt_BR",
+"zh_CN", etc.
+
+Then edit the automatically generated copyright info in your new XX.po
+to be correct, e.g. for Icelandic:
+
+    @@ -1,6 +1,6 @@
+    -# Icelandic translations for PACKAGE package.
+    -# Copyright (C) 2010 THE PACKAGE'S COPYRIGHT HOLDER

+just "Git":
+
+    perl -pi -e 's/(?<="Project-Id-Version: )PACKAGE VERSION/Git/' XX.po
+
+Once you are done testing the translation (see below), commit the result
+and ask the l10n coordinator to pull from you.
+
+
+Updating a XX.po file
+---------------------
+
+(This is done by the language teams).
+
+If you are replacing translation strings in an existing XX.po file to
+improve the translation, just edit the file.
+
+If there's an existing XX.po file for your language, but the repository
+of the l10n coordinator has newer po/git.pot file, you would need to first
+pull from the l10n coordinator (see the beginning of this document for its
+URL), and then update the existing translation by running:
+
+    msgmerge --add-location --backup=off -U XX.po git.pot
+
+in the po/ directory, where XX.po is the file you want to update.
+
+Once you are done testing the translation (see below), commit the result
+and ask the l10n coordinator to pull from you.
+
+
+Testing your changes
+--------------------
+
+(This is done by the language teams, after creating or updating XX.po file).
+
+Before you submit your changes go back to the top-level and do:
+
+    make
+
+On systems with GNU gettext (i.e. not Solaris) this will compile your
+changed PO file with `msgfmt --check`, the --check option flags many
+common errors, e.g. missing printf format strings, or translated
+messages that deviate from the originals in whether they begin/end
+with a newline or not.
+
+
+Marking strings for translation
+-------------------------------
+
+(This is done by the core developers).
+
+Before strings can be translated they first have to be marked for
+translation.
+
+Git uses an internationalization interface that wraps the system's
+gettext library, so most of the advice in your gettext documentation
+(on GNU systems `info gettext` in a terminal) applies.
+
+General advice:
+
+ - Don't mark everything for translation, only strings which will be
+   read by humans (the porcelain interface) should be translated.
+
+   The output from Git's plumbing utilities will primarily be read by
+   programs and would break scripts under non-C locales if it was
+   translated. Plumbing strings should not be translated, since
+   they're part of Git's API.
+
+ - Adjust the strings so that they're easy to translate. Most of the
+   advice in `info '(gettext)Preparing Strings'` applies here.
+
+ - If something is unclear or ambiguous you can use a "TRANSLATORS"
+   comment to tell the translators what to make of it. These will be
+   extracted by xgettext(1) and put in the po/*.po files, e.g. from
+   git-am.sh:
+
+       # TRANSLATORS: Make sure to include [y], [n], [e], [v] and [a]
+       # in your translation. The program will only accept English
+       # input at this point.
+       gettext "Apply? [y]es/[n]o/[e]dit/[v]iew patch/[a]ccept all "
+
+   Or in C, from builtin/revert.c:
+
+       /* TRANSLATORS: %s will be "revert" or "cherry-pick" */
+       die(_("%s: Unable to write new index file"), action_name(opts));
+
+We provide wrappers for C, Shell and Perl programs. Here's how they're
+used:
+
+C:
+
+ - Include builtin.h at the top, it'll pull in gettext.h, which
+   defines the gettext interface. Consult with the list if you need to
+   use gettext.h directly.
+
+ - The C interface is a subset of the normal GNU gettext
+   interface. We currently export these functions:
+
+   - _()
+
+    Mark and translate a string. E.g.:
+
+        printf(_("HEAD is now at %s"), hex);
+
+   - Q_()
+
+    Mark and translate a plural string. E.g.:
+
+        printf(Q_("%d commit", "%d commits", number_of_commits));
+
+    This is just a wrapper for the ngettext() function.
+
+   - N_()
+
+    A no-op pass-through macro for marking strings inside static
+    initializations, e.g.:
+
+        static const char *reset_type_names[] = {
+            N_("mixed"), N_("soft"), N_("hard"), N_("merge"), N_("keep"), NULL
+        };
+
+    And then, later:
+
+        die(_("%s reset is not allowed in a bare repository"),
+               _(reset_type_names[reset_type]));
+
+    Here _() couldn't have statically determined what the translation
+    string will be, but since it was already marked for translation
+    with N_() the look-up in the message catalog will succeed.
+
+Shell:
+
+ - The Git gettext shell interface is just a wrapper for
+   gettext.sh. Import it right after git-sh-setup like this:
+
+       . git-sh-setup
+       . git-sh-i18n
+
+   And then use the gettext or eval_gettext functions:
+
+       # For constant interface messages:
+       gettext "A message for the user"; echo
+
+       # To interpolate variables:
+       details="oh noes"
+       eval_gettext "An error occured: \$details"; echo
+
+   In addition we have wrappers for messages that end with a trailing
+   newline. I.e. you could write the above as:
+
+       # For constant interface messages:
+       gettextln "A message for the user"
+
+       # To interpolate variables:
+       details="oh noes"
+       eval_gettextln "An error occured: \$details"
+
+   More documentation about the interface is available in the GNU info
+   page: `info '(gettext)sh'`. Looking at git-am.sh (the first shell
+   command to be translated) for examples is also useful:
+
+       git log --reverse -p --grep=i18n git-am.sh
+
+Perl:
+
+ - The Git::I18N module provides a limited subset of the
+   Locale::Messages functionality, e.g.:
+
+       use Git::I18N;
+       print __("Welcome to Git!\n");
+       printf __("The following error occured: %s\n"), $error;
+
+   Run `perldoc perl/Git/I18N.pm` for more info.
+
+
+Testing marked strings
+----------------------
+
+Even if you've correctly marked porcelain strings for translation
+something in the test suite might still depend on the US English
+version of the strings, e.g. to grep some error message or other
+output.
+
+To smoke out issues like these Git can be compiled with gettext poison
+support, at the top-level:
+
+    make GETTEXT_POISON=YesPlease
+
+That'll give you a git which emits gibberish on every call to
+gettext. It's obviously not meant to be installed, but you should run
+the test suite with it:
+
+    cd t && prove -j 9 ./t[0-9]*.sh
+
+If tests break with it you should inspect them manually and see if
+what you're translating is sane, i.e. that you're not translating
+plumbing output.
+
+If not you should replace calls to grep with test_i18ngrep, or
+test_cmp calls with test_i18ncmp. If that's not enough you can skip
+the whole test by making it depend on the C_LOCALE_OUTPUT
+prerequisite. See existing test files with this prerequisite for
+examples.

-Smoke testing
--------------
-
-The Git test suite has support for smoke testing. Smoke testing is
-when you submit the results of a test run to a central server for
-analysis and aggregation.
-
-Running a smoke tester is an easy and valuable way of contributing to
-Git development, particularly if you have access to an uncommon OS on
-obscure hardware.
-
-After building Git you can generate a smoke report like this in the
-"t" directory:
-
-    make clean smoke
-
-You can also pass arguments via the environment. This should make it
-faster:
-
-    GIT_TEST_OPTS='--root=/dev/shm' TEST_JOBS=10 make clean smoke
-
-The "smoke" target will run the Git test suite with Perl's
-"TAP::Harness" module, and package up the results in a .tar.gz archive
-with "TAP::Harness::Archive". The former is included with Perl v5.10.1
-or later, but you'll need to install the latter from the CPAN. See the
-"Test coverage" section above for how you might do that.
-
-Once the "smoke" target finishes you'll see a message like this:
-
-    TAP Archive created at <path to git>/t/test-results/git-smoke.tar.gz
-
-To upload the smoke report you need to have curl(1) installed, then
-do:
-
-    make smoke_report
-
-To upload the report anonymously. Hopefully that'll return something
-like "Reported #7 added.".
-
-If you're going to be uploading reports frequently please request a
-user account by E-Mailing gitsmoke@v.nix.is. Once you have a username
-and password you'll be able to do:
-
-    SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> make smoke_report
-
-You can also add an additional comment to attach to the report, and/or
-a comma separated list of tags:
-
-    SMOKE_USERNAME=<username> SMOKE_PASSWORD=<password> \
-        SMOKE_COMMENT=<comment> SMOKE_TAGS=<tags> \
-        make smoke_report
-
-Once the report is uploaded it'll be made available at
-http://smoke.git.nix.is, here's an overview of Recent Smoke Reports
-for Git:
-
-    http://smoke.git.nix.is/app/projects/smoke_reports/1
-
-The reports will also be mirrored to GitHub every few hours:
-
-    http://github.com/gitsmoke/smoke-reports
-
-The Smolder SQLite database is also mirrored and made available for
-download:
-
-    http://github.com/gitsmoke/smoke-database
-
-Note that the database includes hashed (with crypt()) user passwords
-and E-Mail addresses. Don't use a valuable password for the smoke
-service if you have an account, or an E-Mail address you don't want to
-be publicly known. The user accounts are just meant to be convenient
-labels, they're not meant to be secure.

+Git performance tests
+=====================
+
+This directory holds performance testing scripts for git tools.  The
+first part of this document describes the various ways in which you
+can run them.
+
+When fixing the tools or adding enhancements, you are strongly
+encouraged to add tests in this directory to cover what you are
+trying to fix or enhance.  The later part of this short document
+describes how your test scripts should be organized.
+
+
+Running Tests
+-------------
+
+The easiest way to run tests is to say "make".  This runs all
+the tests on the current git repository.
+
+    === Running 2 tests in this tree ===
+    [...]
+    Test                                     this tree
+    ---------------------------------------------------------
+    0001.1: rev-list --all                   0.54(0.51+0.02)
+    0001.2: rev-list --all --objects         6.14(5.99+0.11)
+    7810.1: grep worktree, cheap regex       0.16(0.16+0.35)
+    7810.2: grep worktree, expensive regex   7.90(29.75+0.37)
+    7810.3: grep --cached, cheap regex       3.07(3.02+0.25)
+    7810.4: grep --cached, expensive regex   9.39(30.57+0.24)
+
+You can compare multiple repositories and even git revisions with the
+'run' script:
+
+    $ ./run . origin/next /path/to/git-tree p0001-rev-list.sh
+
+where . stands for the current git tree.  The full invocation is
+
+    ./run [<revision|directory>...] [--] [<test-script>...]
+
+A '.' argument is implied if you do not pass any other
+revisions/directories.
+
+You can also manually test this or another git build tree, and then
+call the aggregation script to summarize the results:
+
+    $ ./p0001-rev-list.sh
+    [...]
+    $ GIT_BUILD_DIR=/path/to/other/git ./p0001-rev-list.sh
+    [...]
+    $ ./aggregate.perl . /path/to/other/git ./p0001-rev-list.sh
+
+aggregate.perl has the same invocation as 'run', it just does not run
+anything beforehand.
+
+You can set the following variables (also in your config.mak):
+
+    GIT_PERF_REPEAT_COUNT
+	Number of times a test should be repeated for best-of-N
+	measurements.  Defaults to 5.
+
+    GIT_PERF_MAKE_OPTS
+	Options to use when automatically building a git tree for
+	performance testing.  E.g., -j6 would be useful.
+
+    GIT_PERF_REPO
+    GIT_PERF_LARGE_REPO
+	Repositories to copy for the performance tests.  The normal
+	repo should be at least git.git size.  The large repo should
+	probably be about linux-2.6.git size for optimal results.
+	Both default to the git.git you are running from.
+
+You can also pass the options taken by ordinary git tests; the most
+useful one is:
+
+--root=<directory>::
+	Create "trash" directories used to store all temporary data during
+	testing under <directory>, instead of the t/ directory.
+	Using this option with a RAM-based filesystem (such as tmpfs)
+	can massively speed up the test suite.
+
+
+Naming Tests
+------------
+
+The performance test files are named as:
+
+	pNNNN-commandname-details.sh
+
+where N is a decimal digit.  The same conventions for choosing NNNN as
+for normal tests apply.
+
+
+Writing Tests
+-------------
+
+The perf script starts much like a normal test script, except it
+sources perf-lib.sh:
+
+	#!/bin/sh
+	#
+	# Copyright (c) 2005 Junio C Hamano
+	#
+
+	test_description='xxx performance test'
+	. ./perf-lib.sh
+
+After that you will want to use some of the following:
+
+	test_perf_default_repo  # sets up a "normal" repository
+	test_perf_large_repo    # sets up a "large" repository
+
+	test_perf_default_repo sub  # ditto, in a subdir "sub"
+
+        test_checkout_worktree  # if you need the worktree too
+
+At least one of the first two is required!
+
+You can use test_expect_success as usual.  For actual performance
+tests, use
+
+	test_perf 'descriptive string' '
+		command1 &&
+		command2
+	'
+
+test_perf spawns a subshell, for lack of better options.  This means
+that
+
+* you _must_ export all variables that you need in the subshell
+
+* you _must_ flag all variables that you want to persist from the
+  subshell with 'test_export':
+
+	test_perf 'descriptive string' '
+		foo=$(git rev-parse HEAD) &&
+		test_export foo
+	'
+
+  The so-exported variables are automatically marked for export in the
+  shell executing the perf test.  For your convenience, test_export is
+  the same as export in the main shell.
+
+  This feature relies on a bit of magic using 'set' and 'source'.
+  While we have tried to make sure that it can cope with embedded
+  whitespace and other special characters, it will not work with
+  multi-line data.

+
+This is a tool for authors of external helper tools to sanity-check
+their helpers. If you have written the "git-credential-foo" helper,
+you check it with:
+
+  make GIT_TEST_CREDENTIAL_HELPER=foo t0303-credential-external.sh
+
+This assumes that your helper is capable of both storing and
+retrieving credentials (some helpers may be read-only, and they will
+fail these tests).
+
+Please note that the individual tests do not verify all of the
+preconditions themselves, but rather build on each other. A failing
+test means that tests later in the sequence can return false "OK"
+results.
+
+If your helper supports time-based expiration with a configurable
+timeout, you can test that feature with:
+
+  make GIT_TEST_CREDENTIAL_HELPER=foo \
+       GIT_TEST_CREDENTIAL_HELPER_TIMEOUT="foo --timeout=1" \
+       t0303-credential-external.sh
+
+If your helper requires additional setup before the tests are started,
+you can set GIT_TEST_CREDENTIAL_HELPER_SETUP to a sequence of shell
+commands.

-string_pool API
-===============
-
-The string_pool API provides facilities for replacing strings
-with integer keys that can be more easily compared and stored.
-The facilities are designed so that one could teach Git without
-too much trouble to store the information needed for these keys to
-remain valid over multiple executions.
-
-Functions
----------
-
-pool_intern::
-	Include a string in the string pool and get its key.
-	If that string is already in the pool, retrieves its
-	existing key.
-
-pool_fetch::
-	Retrieve the string associated to a given key.
-
-pool_tok_r::
-	Extract the key of the next token from a string.
-	Interface mimics strtok_r.
-
-pool_print_seq::
-	Print a sequence of strings named by key to a file, using the
-	specified delimiter to separate them.
-
-	If NULL (key ~0) appears in the sequence, the sequence ends
-	early.
-
-pool_tok_seq::
-	Split a string into tokens, storing the keys of segments
-	into a caller-provided array.
-
-	Unless sz is 0, the array will always be ~0-terminated.
-	If there is not enough room for all the tokens, the
-	array holds as many tokens as fit in the entries before
-	the terminating ~0.  Return value is the index after the
-	last token, or sz if the tokens did not fit.
-
-pool_reset::
-	Deallocate storage for the string pool.

-Motivation
-==========
-
-Treaps provide a memory-efficient binary search tree structure.
-Insertion/deletion/search are about as about as fast in the average
-case as red-black trees and the chances of worst-case behavior are
-vanishingly small, thanks to (pseudo-)randomness.  The bad worst-case
-behavior is a small price to pay, given that treaps are much simpler
-to implement.
-
-API
-===
-
-The trp API generates a data structure and functions to handle a
-large growing set of objects stored in a pool.
-
-The caller:
-
-. Specifies parameters for the generated functions with the
-  trp_gen(static, foo_, ...) macro.
-
-. Allocates a `struct trp_root` variable and sets it to {~0}.
-
-. Adds new nodes to the set using `foo_insert`.  Any pointers
-  to existing nodes cannot be relied upon any more, so the caller
-  might retrieve them anew with `foo_pointer`.
-
-. Can find a specific item in the set using `foo_search`.
-
-. Can iterate over items in the set using `foo_first` and `foo_next`.
-
-. Can remove an item from the set using `foo_remove`.
-
-Example:
-
-----
-struct ex_node {
-	const char *s;
-	struct trp_node ex_link;
-};
-static struct trp_root ex_base = {~0};
-obj_pool_gen(ex, struct ex_node, 4096);
-trp_gen(static, ex_, struct ex_node, ex_link, ex, strcmp)
-struct ex_node *item;
-
-item = ex_pointer(ex_alloc(1));
-item->s = "hello";
-ex_insert(&ex_base, item);
-item = ex_pointer(ex_alloc(1));
-item->s = "goodbye";
-ex_insert(&ex_base, item);
-for (item = ex_first(&ex_base); item; item = ex_next(&ex_base, item))
-	printf("%s\n", item->s);
-----
-
-Functions
----------
-
-trp_gen(attr, foo_, node_type, link_field, pool, cmp)::
-
-	Generate a type-specific treap implementation.
-+
-. The storage class for generated functions will be 'attr' (e.g., `static`).
-. Generated function names are prefixed with 'foo_' (e.g., `treap_`).
-. Treap nodes will be of type 'node_type' (e.g., `struct treap_node`).
-  This type must be a struct with at least one `struct trp_node` field
-  to point to its children.
-. The field used to access child nodes will be 'link_field'.
-. All treap nodes must lie in the 'pool' object pool.
-. Treap nodes must be totally ordered by the 'cmp' relation, with the
-  following prototype:
-+
-int (*cmp)(node_type \*a, node_type \*b)
-+
-and returning a value less than, equal to, or greater than zero
-according to the result of comparison.
-
-node_type {asterisk}foo_insert(struct trp_root *treap, node_type \*node)::
-
-	Insert node into treap.  If inserted multiple times,
-	a node will appear in the treap multiple times.
-+
-The return value is the address of the node within the treap,
-which might differ from `node` if `pool_alloc` had to call
-`realloc` to expand the pool.
-
-void foo_remove(struct trp_root *treap, node_type \*node)::
-
-	Remove node from treap.  Caller must ensure node is
-	present in treap before using this function.
-
-node_type *foo_search(struct trp_root \*treap, node_type \*key)::
-
-	Search for a node that matches key.  If no match is found,
-	result is NULL.
-
-node_type *foo_nsearch(struct trp_root \*treap, node_type \*key)::
-
-	Like `foo_search`, but if the key is missing return what
-	would be key's successor, were key in treap (NULL if no
-	successor).
-
-node_type *foo_first(struct trp_root \*treap)::
-
-	Find the first item from the treap, in sorted order.
-
-node_type *foo_next(struct trp_root \*treap, node_type \*node)::
-
-	Find the next item.
