 GLOBAL SETTINGS
 ---------------
+about-filter::
+	Specifies a command which will be invoked to format the content of

+	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"

+	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.
