 CGITRC(5)
 ========
 
 
 NAME
 ----
 cgitrc - runtime configuration for cgit
 
 
 SYNOPSIS
 --------
 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.
 
 
+LOCATION
+--------
+The default location of cgitrc, defined at compile time, is /etc/cgitrc. At
+runtime, cgit will consult the environment variable CGIT_CONFIG and, if
+defined, use its value instead.
+
+
 GLOBAL SETTINGS
 ---------------
 about-filter::
 	Specifies a command which will be invoked to format the content of
 	about pages (both top-level and for each repository). The command will
 	get the content of the about-file on its STDIN, and the STDOUT from the
 	command will be included verbatim on the about page. Default value:
 	none.
 
 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.
 
 commit-filter::
 	Specifies a command which will be invoked to format commit messages.
 	The command will get the message on its STDIN, and the STDOUT from the
 	command will be included verbatim as the commit message, i.e. this can
 	be used to implement bugtracker integration. Default value: none.
 
 css::
 	Url which specifies the css document to include in all cgit pages.
 	Default value: "/cgit.css".
 
 embedded::
 	Flag which, when set to "1", will make cgit generate a html fragment
 	suitable for embedding in other html pages. Default value: none. See
 	also: "noheader".
 	
 enable-index-links::
