The code source is managed with darcs. The natural way to get a local copy of the code is:
darcs get --partial http://dev.39mm.net/darcs/megawave-4
I added today a subversion frontend. So you can also get a local copy of the code with:
svn checkout http://dev.39mm.net/svn/megawave-4
The darcs -> svn sync is performed every night.
