 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"

 REPOSITORY SETTINGS
 -------------------
+repo.about-filter::
+        Override the default about-filter. Default value: <about-filter>.

 repo.clone-url::
         A list of space-separated urls which can be used to clone this repo.
