git checkout whizbang-branch
git rebase master
+Working on a maintenance branch from git
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The matplotlib maintenance branches are also available through git.
+(Note that the ``git svn init`` line in the instructions above was
+updated to make this possible. If you created your git mirror without
+a ``--branches`` option, you will need to perform all of the steps
+again in a new directory).
+
+You can see which branches are available with::
+
+ git branch -a
+
+To switch your working copy to the 0.98.5 maintenance branch::
+
+ git checkout v0_98_5_maint
+
+Then you probably want to (as above) create a new local branch based
+on that branch::
+
+ git checkout -b whizbang-branch
+
+When you ``git svn dcommit`` from a maintenance branch, it will commit
+to that branch, not to the trunk.
+
+While it should theoretically be possible to perform merges from a git
+maintenance branch to a git trunk and then commit those changes back
+to the SVN trunk, I have yet to find the magic incantation to make
+that work. However, svnmerge as described `above <svn-merge>`_ can be
+used and in fact works quite well.
+
A note about git write access
