Setting up Subversion for Developer Use
The first thing you will want to do is setup the ssh access to svn.gna.org. If you cannot type
svn list svn+ssh://svn.gna.org/svn/gnustep/devmodules
without having to type a password or in some way change the above command, you will need to visit the Svn SSH Setup page (this includes if you have to specify a different user).
