 This is ideally suited for read-only updates, ie pulling from git repositories.
 
 OPTIONS
 -------
+--export-all::
+	Allow pulling from all directories that look like GIT repositories
+	(have the 'objects' subdirectory and a 'HEAD' file), even if they
+	do not have the 'git-daemon-export-ok' file.
+
 --inetd::
 	Have the server run as an inetd service.
 
 --port::
 	Listen on an alternative port.
 
+--init-timeout::
+	Timeout between the moment the connection is established and the
+	client request is received (typically a rather low value, since
+	that should be basically immediate).
+
+--timeout::
+	Timeout for specific client sub-requests. This includes the time
+	it takes for the server to process the sub-request and time spent
+	waiting for next client's request.
+
 --syslog::
 	Log to syslog instead of stderr. Note that this option does not imply
 	--verbose, thus by default only error conditions will be logged.
