+git-repo-config(1)
+==================
+
+NAME
+----
+git-repo-config - Get and set options in .git/config.
+
+
+SYNOPSIS
+--------
+'git-repo-config' name [value [value_regex]]
+'git-repo-config' --replace-all name [value [value_regex]]
+'git-repo-config' --get name [value_regex]
+'git-repo-config' --get-all name [value_regex]
+'git-repo-config' --unset name [value_regex]
+'git-repo-config' --unset-all name [value_regex]
+
+DESCRIPTION
+-----------
+You can query/set/replace/unset options with this command. The name is
+actually the section and the key separated by a dot, and the value will be
+escaped.
+
+If you want to set/unset an option which can occor on multiple lines, you
+should provide a POSIX regex for the value. If you want to handle the lines
+*not* matching the regex, just prepend a single exlamation mark in front
+(see EXAMPLES).
+
+This command will fail if
+
+. .git/config is invalid,
+. .git/config can not be written to,
+. no section was provided,
+. the section or key is invalid,
+. you try to unset an option which does not exist, or
+. you try to unset/set an option for which multiple lines match.
+
+
+OPTIONS
+-------
+
+--replace-all::
+ Default behaviour is to replace at most one line. This replaces
+ all lines matching the key (and optionally the value_regex)
+
+--get::
+ Get the value for a given key (optionally filtered by a regex
+ matching the value).
+
+--get-all::
+ Like get, but does not fail if the number of values for the key
+ is not exactly one.
+
+--unset::
+ Remove the line matching the key from .git/config.
+
+--unset-all::
+ Remove all matching lines from .git/config.
+
+
+EXAMPLE
+-------
+
+Given a .git/config like this:
+
+ #
+ # This is the config file, and
+ # a '#' or ';' character indicates
+ # a comment
+ #
+
+ ; core variables
+ [core]
+ ; Don't trust file modes
+ filemode = false
+
+ ; Our diff algorithm
+ [diff]
+ external = "/usr/local/bin/gnu-diff -u"
+ renames = true
+
+ ; Proxy settings
+ [proxy]
+ command="ssh" for "ssh://kernel.org/"
+ command="proxy-command" for kernel.org
+ command="myprotocol-command" for "my://"
+ command=default-proxy ; for all the rest
+
+you can set the filemode to true with
+
+------------
+% git repo-config core.filemode true
+------------
+
+The hypothetic proxy command entries actually have a postfix to discern
+to what URL they apply. Here is how to change the entry for kernel.org
+to "ssh".
+
+------------
+% git repo-config proxy.command '"ssh" for kernel.org' 'for kernel.org$'
+------------
+
+This makes sure that only the key/value pair for kernel.org is replaced.
+
+To delete the entry for renames, do
+
+------------
+% git repo-config --unset diff.renames
+------------
+
+If you want to delete an entry for a multivar (like proxy.command above),
+you have to provide a regex matching the value of exactly one line.
+
+To query the value for a given key, do
+
+------------
+% git repo-config --get core.filemode
+------------
+
+or
+
+------------
+% git repo-config core.filemode
+------------
+
+or, to query a multivar:
+
+------------
+% git repo-config --get proxy.command "for kernel.org$"
+------------
+
+If you want to know all the values for a multivar, do:
+
+------------
+% git repo-config --get-all proxy.command
+------------
+
+If you like to live dangerous, you can replace *all* proxy.commands by a
+new one with
+
+------------
+% git repo-config --replace-all proxy.command ssh
+------------
+
+However, if you really only want to replace the line for the default proxy,
+i.e. the one without a "for ..." postfix, do something like this:
+
+------------
+% git repo-config proxy.command ssh '! for '
+------------
+
+To actually match only values with an exclamation mark, you have to
+
+------------
+% git repo-config section.key value '[!]'
+------------

+From: Junio C Hamano <junkio@cox.net>
+Subject: control access to branches.
+Date: Thu, 17 Nov 2005 23:55:32 -0800
+Message-ID: <7vfypumlu3.fsf@assigned-by-dhcp.cox.net>
+Abstract: An example hooks/update script is presented to
+ implement repository maintenance policies, such as who can push
+ into which branch and who can make a tag.
+
+When your developer runs git-push into the repository,
+git-receive-pack is run (either locally or over ssh) as that
+developer, so is hooks/update script. Quoting from the relevant
+section of the documentation:
+
+ Before each ref is updated, if $GIT_DIR/hooks/update file exists
+ and executable, it is called with three parameters:
+
+ $GIT_DIR/hooks/update refname sha1-old sha1-new
+
+ The refname parameter is relative to $GIT_DIR; e.g. for the
+ master head this is "refs/heads/master". Two sha1 are the
+ object names for the refname before and after the update. Note
+ that the hook is called before the refname is updated, so either
+ sha1-old is 0{40} (meaning there is no such ref yet), or it
+ should match what is recorded in refname.
+
+So if your policy is (1) always require fast-forward push
+(i.e. never allow "git-push repo +branch:branch"), (2) you
+have a list of users allowed to update each branch, and (3) you
+do not let tags to be overwritten, then:
+
+ #!/bin/sh
+ # This is a sample hooks/update script, written by JC
+ # in his e-mail buffer, so naturally it is not tested
+ # but hopefully would convey the idea.
+
+ umask 002
+ case "$1" in
+ refs/tags/*)
+ # No overwriting an existing tag
+ if test -f "$GIT_DIR/$1"
+ then
+ exit 1
+ fi
+ ;;
+ refs/heads/*)
+ # No rebasing or rewinding
+ if expr "$2" : '0*$' >/dev/null
+ then
+ # creating a new branch
+ ;
+ else
+ # updating -- make sure it is a fast forward
+ mb=`git-merge-base "$2" "$3"`
+ case "$mb,$2" in
+ "$2,$mb")
+ ;; # fast forward -- happy
+ *)
+ exit 1 ;; # unhappy
+ esac
+ fi
+ ;;
+ *)
+ # No funny refs allowed
+ exit 1
+ ;;
+ esac
+
+ # Is the user allowed to update it?
+ me=`id -u -n` ;# e.g. "junio"
+ while read head_pattern users
+ do
+ if expr "$1" : "$head_pattern" >/dev/null
+ then
+ case " $users " in
+ *" $me "*)
+ exit 0 ;; # happy
+ ' * ')
+ exit 0 ;; # anybody
+ esac
+ fi
+ done
+ exit 1
+
+For the sake of simplicity, I assumed that you keep something
+like this in $GIT_DIR/info/allowed-pushers file:
+
+ refs/heads/master junio
+ refs/heads/cogito$ pasky
+ refs/heads/bw/ linus
+ refs/heads/tmp/ *
+ refs/tags/v[0-9]* junio
+
+With this, Linus can push or create "bw/penguin" or "bw/zebra"
+or "bw/panda" branches, Pasky can do only "cogito", and I can do
+master branch and make versioned tags. And anybody can do
+tmp/blah branches. This assumes all the users are in a single
+group that can write into $GIT_DIR/ and underneath.
