-[[!meta title="Revision Control Systems"]]
-
-Ikiwiki supports using several revision control systems for storing page
-histories.
-
-Ikiwiki started out supporting only [[Subversion|svn]], but the interface
-ikiwiki uses to a revision control system is sufficiently simple and
-generic that it can be adapted to work with many systems by writing a
-[[plugin|plugins/write]]. These days, most people use [[git]].
-
-While all supported revision control systems work well enough for basic
-use, some advanced or special features are not supported in all of them.
-The table below summarises this for each revision control system and
-links to more information about each.

-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.
