Information about using the Arabeyes CVS Repository can be found in the Arabeyes CVS HOWTO.
The projects on Arabeyes can be checked out via the 'anoncvs' account as follows:
$ cvs -d:pserver:anoncvs@cvs.arabeyes.org:/home/arabeyes/cvs login
The password is 'anoncvs' (just like the login name).
$ cvs -z3 -d:pserver:anoncvs@cvs.arabeyes.org:/home/arabeyes/cvs co projname
You can also view the CVS content via the web interface here.
