## [darcs](http://darcs.net/) (not yet included)
Support for using darcs as a backend is being worked on by [Thomas
-Schwinge](mailto:tschwinge@gnu.org).
+Schwinge](mailto:tschwinge@gnu.org), although development is on hold curretly.
+There is a patch in the [[patchqueue]].
### How will it work internally?
FILE' (please see the relevant comment in mergepast for more details), so I
had to invent an ugly hack just for the purpose.
-## [Mercurial](http://www.selenic.com/mercurial/)
+By design, Git backend uses a "master-clone" repository pair approach in contrast
+to the single repository approach (here, _clone_ may be considered as the working
+copy of a fictious web user). Even though a single repository implementation is
+possible, it somewhat increases the code complexity of backend (I couldn't figure
+out a uniform method which doesn't depend on the prefered repository model, yet).
+By exploiting the fact that the master repo and _web user_'s repo (`srcdir`) are all
+on the same local machine, I suggest to create the latter with the "`git clone -l -s`"
+command to save disk space.
+
+Note that, as a rule of thumb, you should always put the rcs wrapper (`post-update`)
+into the master repository (`.git/hooks/`) as can be noticed in the Git wrappers of
+the sample [[ikiwiki.setup]].
+
+## [[Mercurial]]
The Mercurial backend is still in a early phase, so it may not be mature
enough, but it should be simple to understand and use.
CGI operates on M. rcs_commit() will commit directly in M.
