Replace cgitrc with cgitrc.5.txt

The new file describes all cgitrc options in a more structured manner then
the cgitrc example file and it might also work as the source for a cgitrc
man page.

+
+NAME
+----
+	cgitrc - runtime configuration for cgit
+
+
+DESCRIPTION
+-----------
+Cgitrc contains all runtime settings for cgit, including the list of git
+repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank
+lines, and lines starting with '#', are ignored.
+
+
+GLOBAL SETTINGS
+---------------
+agefile
+	Specifies a path, relative to each repository path, which can be used
+	to specify the date and time of the youngest commit in the repository.
+	The first line in the file is used as input to the "parse_date"
+	function in libgit. Recommended timestamp-format is "yyyy-mm-dd
+	hh:mm:ss". Default value: "info/web/last-modified".
+
+cache-root
+	Path used to store the cgit cache entries. Default value:
+	"/var/cache/cgit".
+
+cache-dynamic-ttl
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of repository pages accessed without a fixed SHA1. Default
+	value: "5".
+
+cache-repo-ttl
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of the repository summary page. Default value: "5".
+
+cache-root-ttl
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of the repository index page. Default value: "5".
+
+cache-size
+	The maximum number of entries in the cgit cache. Default value: "0"
+	(i.e. caching is disabled).
+
+cache-static-ttl
+	Number which specifies the time-to-live, in minutes, for the cached
+	version of repository pages accessed with a fixed SHA1. Default value:
+	"5".
+
+clone-prefix
+	Space-separated list of common prefixes which, when combined with a
+	repository url, generates valid clone urls for the repository. This
+	setting is only used if `repo.clone-url` is unspecified. Default value:
+	none.
+
+css
+	Url which specifies the css document to include in all cgit pages.
+	Default value: "/cgit.css".
+
+enable-index-links
+	Flag which, when set to "1", will make cgit generate extra links for
+	each repo in the repository index (specifically, to the "summary",
+	"commit" and "tree" pages). Default value: "0".
+
+enable-log-filecount
+	Flag which, when set to "1", will make cgit print the number of
+	modified files for each commit on the repository log page. Default
+	value: "0".
+
+enable-log-linecount
+	Flag which, when set to "1", will make cgit print the number of added
+	and removed lines for each commit on the repository log page. Default
+	value: "0".
+
+favicon
+	Url used as link to a shortcut icon for cgit. If specified, it is
+	suggested to use the value "/favicon.ico" since certain browsers will
+	ignore other values. Default value: none.
+
+footer
+	The content of the file specified with this option will be included
+	verbatim at the bottom of all pages (i.e. it replaces the standard
+	"generated by..." message. Default value: none.
+
+include
+	Name of a configfile to include before the rest of the current config-
+	file is parsed. Default value: none.
+
+index-header
+	The content of the file specified with this option will be included
+	verbatim above the repository index. This setting is deprecated, and
+	will not be supported by cgit-1.0 (use root-readme instead). Default
+	value: none.
+
+index-info
+	The content of the file specified with this option will be included
+	verbatim below the heading on the repository index page. This setting
+	is deprecated, and will not be supported by cgit-1.0 (use root-desc
+	instead). Default value: none.
+
+local-time
+	Flag which, if set to "1", makes cgit print commit and tag times in the
+	servers timezone. Default value: "0".
+
+logo
+	Url which specifies the source of an image which will be used as a logo
+	on all cgit pages.
+
+logo-link
+	Url loaded when clicking on the cgit logo image. If unspecified the
+	calculated url of the repository index page will be used. Default
+	value: none.
+
+max-commit-count
+	Specifies the number of entries to list per page in "log" view. Default
+	value: "50".
+
+max-message-length
+	Specifies the maximum number of commit message characters to display in
+	"log" view. Default value: "80".
+
+max-repo-count
+	Specifies the number of entries to list per page on the	repository
+	index page. Default value: "50".
+
+max-repodesc-length
+	Specifies the maximum number of repo description characters to display
+	on the repository index page. Default value: "80".
+
+module-link
+	Text which will be used as the formatstring for a hyperlink when a
+	submodule is printed in a directory listing. The arguments for the
+	formatstring are the path and SHA1 of the submodule commit. Default
+	value: "./?repo=%s&page=commit&id=%s"
+
+nocache
+	If set to the value "1" caching will be disabled. This settings is
+	deprecated, and will not be honored starting with cgit-1.0. Default
+	value: "0".
+
+renamelimit
+	Maximum number of files to consider when detecting renames. The value
+	 "-1" uses the compiletime value in git (for further info, look at
+	  `man git-diff`). Default value: "-1".
+
+repo.group
+	A value for the current repository group, which all repositories
+	specified after this setting will inherit. Default value: none.
+
+robots
+	Text used as content for the "robots" meta-tag. Default value:
+	"index, nofollow".
+
+root-desc
+	Text printed below the heading on the repository index page. Default
+	value: "a fast webinterface for the git dscm".
+
+root-readme:
+	The content of the file specified with this option will be included
+	verbatim below the "about" link on the repository index page. Default
+	value: none.
+
+root-title
+	Text printed as heading on the repository index page. Default value:
+	"Git Repository Browser".
+
+snapshots
+	Text which specifies the default (and allowed) set of snapshot formats
+	supported by cgit. The value is a space-separated list of zero or more
+	of the following values:
+		"tar"		uncompressed tar-file
+		"tar.gz"	gzip-compressed tar-file
+		"tar.bz2"	bzip-compressed tar-file
+		"zip"		zip-file
+	Default value: none.
+
+summary-branches
+	Specifies the number of branches to display in the repository "summary"
+	view. Default value: "10".
+
+summary-log
+	Specifies the number of log entries to display in the repository
+	"summary" view. Default value: "10".
+
+summary-tags
+	Specifies the number of tags to display in the repository "summary"
+	view. Default value: "10".
+
+virtual-root
+	Url which, if specified, will be used as root for all cgit links. It
+	will also cause cgit to generate 'virtual urls', i.e. urls like
+	'/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
+	value: none.
+	NOTE: cgit has recently learned how to use PATH_INFO to achieve the
+	same kind of virtual urls, so this option will probably be deprecated.
+
+REPOSITORY SETTINGS
+-------------------
+repo.clone-url
+	A list of space-separated urls which can be used to clone this repo.
+	Default value: none.
+
+repo.defbranch
+	The name of the default branch for this repository. If no such branch
+	exists in the repository, the first branch name (when sorted) is used
+	as default instead. Default value: "master".
+
+repo.desc
+	The value to show as repository description. Default value: none.
+
+repo.enable-log-filecount
+	A flag which can be used to disable the global setting
+	`enable-log-filecount'. Default value: none.
+
+repo.enable-log-linecount
+	A flag which can be used to disable the global setting
+	`enable-log-linecount'. Default value: none.
+
+repo.name
+	The value to show as repository name. Default value: <repo.url>.
+
+repo.owner
+	A value used to identify the owner of the repository. Default value:
+	none.
+
+repo.path
+	An absolute path to the repository directory. For non-bare repositories
+	this is the .git-directory. Default value: none.
+
+repo.readme
+	A path (relative to <repo.path>) which specifies a file to include
+	verbatim as the "About" page for this repo. Default value: none.
+
+repo.snapshots
+	A mask of allowed snapshot-formats for this repo, restricted by the
+	"snapshots" global setting. Default value: <snapshots>.
+
+repo.url
+	The relative url used to access the repository. This must be the first
+	setting specified for each repo. Default value: none.
+

+BUGS
+----
+Comments currently cannot appear on the same line as a setting; the comment
+will be included as part of the value. E.g. this line:
+
+	robots=index  # allow indexing
+
+will generate the following html element:
+
+	<meta name='robots' content='index  # allow indexing'/>
