K-Meleon uses CVS as its revision control system. You can access the repository using any CVS client or through the Web interface.
If you want to use standard CVS, first you have to supply your login details.
cvs -d:pserver:anonymous»cvs:/cvsroot/kmeleon login
Leave the password empty. You then need to do a checkout.
cvs -z3 -d:pserver:anonymous»cvs:/cvsroot/kmeleon co k-meleon
If later you want to update your local repository, use the cvs update command.
