Darcs does not support branches.  Mercurial does, but they are a  
somewhat unusual feature; instead, people use a different repository  
(as far as I can tell).

We also need to collect on the wiki the commands that we need to  
execute to create these branches in the first place.  It's not trivial  
for git.

Do you have experience with branches in git?  Is it easier to use  
branches, or to have separate repositories and push/pull changes in  
between?
