            -Dmaven.scm.cvs.module=zipdiff

        This project's CVS repository can be checked out through anonymous (pserver) CVS with the following instruction set. When prompted for a password for anonymous, simply press the Enter key.
          cvs -d :pserver:anonymous@cvs.sourceforge.net:/cvsroot/zipdiff login
          
          cvs -z3 -d :pserver:anonymous@cvs.sourceforge.net:/cvsroot/zipdiff co zipdiff
        
Updates from within the module's directory do not need the -d parameter.
For those developers who are stuck behind a corporate firewall, CVSGrab can use the viewcvs web interface to checkout the source code.
