 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.
 
 
 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".
 
+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::
         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::
