ikiwiki-makerepo injects an existing srcdir directory, containing sources for an ikiwiki wiki, into
revision control. It is rarely run directly; consider using ikiwiki --setup /etc/ikiwiki/wiki.setup
instead to set up a wiki.
For git, the repo is created as a bare git repository, and the srcdir is made into a clone of it.
(monotone and darcs are similar.)
For svn and cvs, the repo is the centralized repository, and the srcdir is a checkout of it.
For mercurial and bzr, the srcdir is the only repository set up.
For darcs, the master repo's apply hook will be preconfigured to call a ikiwiki wrapper.
Note that for monotone, you are assumed to already have run "mtn genkey" to generate a key.
