Express Me source code now moved to Mercurial! We do not use Subversion any more.
Mercurial is an open source DVCS (distributed version control system) like Git, and Google code supports Mercurial.
Using Mercurial we get better way of managing source and make branch and merge work much easier.
Install Python 2.5 and Mercurial first. To get the whole source code, you should make a "clone" by using command:
hg clone https://express-me.googlecode.com/hg/ express-me
