``web-edit'' means that a page is edited by using the web (CGI) interface
as opposed to using a editor and the RCS interface.

Subversion was the first RCS to be supported by ikiwiki.

darcs is a distributed RCS, which means that every checkout of a
repository is equal to the repository it was checked-out from. There is

-A patch with full [Git](http://git.or.cz) support is at <http://people.debian.org/~roktas/patches/ikiwiki/git.patch>. Regarding the patch, Recai says:
+Regarding the Git support, Recai says:
I have been testing it for the past few days and it seems satisfactory. I
haven't observed any race condition regarding the concurrent blog commits
part). GIT doesn't have a similar functionality like 'svn merge -rOLD:NEW
FILE' (please see the relevant comment in mergepast for more details), so I
had to invent an ugly hack just for the purpose.

-Some other notes:
-
-- There are two separate helper packages in git.pm. To keep things self
- confined, I haven't split it up.
-
-- I've used a (mini) Debug.pm during the tests and made it a separate file
- for the convenience of others. It relies on the "constant folding"
- feature of Perl, so there shouldn't be a runtime penalty (at least this
- is what the 'perl -MO=Deparse shows', haven't made a real benchmark).
-
-- rcs_notify() has not been implemented yet (I have noticed it after I
- finished the main work).
-
-- GIT backend uses the gitweb for repository browsing (the counterpart of
- ViewCVS).
-
-- There might be some subs in GIT name space which you may prefer to move to
- the main code.
-
-- Due to the reasons explained in the code, I've written an rcs_invoke()
- wrapper. May be there should be a better approach to reach the same
- goal.
-
-- There are some parts which I may change in future, like using a global
- rcs_fatal_error and the ugly error reporting code in _rcs_commit.
-
-- Documentation is missing.
-
-It works for me, but of course in the end, the final decision is yours (due
-to mostly GIT quirks, the implementation is not clean as SVN). Feel free
-to fix/delete/add whatever you want. Hope it doesn't have any serious bug.
