-# History (see http://ikiwiki.info/todo/darcs/):
-#
-# * Thomas Schwinge wrote the original file, implementing only rcs_commit.
-# * Benjamin A'Lee contributed an alternative implementation.
-# * Tuomo Valkonen contributed rcs_getctime and stub rcs_recentchanges.
-# * Simon Michael contributed multiple changes.
-# * Petr Ročkai fixed rcs_recentchanges and added caching to rcs_getctime.
-# * Sven M. Hallberg merged the above and added missing features.

-# We're guaranteed to be the only instance of ikiwiki running at a given
-# time. It is essential that only ikiwiki is working on a particular
-# repository. That means one instance of ikiwiki and it also means that
-# you must not 'darcs push' into this repository, as this might create
-# race conditions, as I understand it.
