 Ikiwiki supports using several revision control systems for storing page
 histories.

+Notes:
+
+* Lack of support in [[ikiwiki-makerepo]] or auto.setup can make it harder to
+  set up a wiki using that revision control system.
+* The `rcs_commit_staged` hook is needed to use [[attachments|plugins/attachment]]
+  or [[plugins/comments]].
+* `rcs_getctime` and `rcs_getmtime` may be implemented in a fast way (ie, one log
+  lookup for all files), or very slowly (one lookup per file).
+* Openid username support allows avoiding display of Google's ugly openids.
 
 There is a page with [[details]] about how the different systems work with
 ikiwiki, for the curious.
