 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.

 REPOSITORY SETTINGS
 -------------------

 repo.clone-url::
         A list of space-separated urls which can be used to clone this repo.
         Default value: none.
