 scan-path::
 	A path which will be scanned for repositories. If caching is enabled,
 	the result will be cached as a cgitrc include-file in the cache
 	directory. If project-list has been defined prior to scan-path,
 	scan-path loads only the directories listed in the file pointed to by
 	project-list. Default value: none. See also: cache-scanrc-ttl,
