+This is mostly based on the Mercurial plugin (in fact, apart from the commands
+being run, only the name of the rcs was changed in rcs_recentchanges, and
+rcs_commit was only changed to work around bzr's lack of a switch to set the
+username). bzr_log could probably be written better by someone better at perl,
+and rcs_getctime and rcs_notify aren't written at all. --[[bma]]
