-		  TYPE          what to do GC on (default: all):
-		                - guix
-		                - deploy
-		                - trash
-		                - tmpdir
-		                - logs
-
-
-		GC the server, deleting old, unusable data, in order to free
-		disk space system-wide.
-
-
-		Examples:
-
-		  Just run it, for all:
-
-		    $ gc
-
-
-		  Cleanup tmpdir:
-
-		    $ gc tmpdir
