-For darcs, the second (one-argument) form turns the given srcdir into a
-darcs master repository with the (new) srcdir inside. Adjust your ikiwiki.setup

-preconfigured to call a (hypothetical) ikiwiki wrapper. The command
-reports the relevant file. Adjust it as needed or remove it if you don't use
-the cgi script.
