+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 hightlighting.
++
+*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_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 `$maxload` to undefined value (`undef`) to turn this feature off.
+The default value is 300.
+
+$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. It's 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 repository in gitweb is path to it's `$GIT_DIR` (it's object
+database) relative to `$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.
+
+various `gitweb.*` config variables (in config)::
+ Read description of `%feature` hash for detailed list, and descriptions.
+ See also "Configuring gitweb features" section in linkgit:gitweb.conf[5]
+
+
+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.
