Anonymous CVS Access :

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. To determine the names of the modules created by this project, you may examine their CVS repository via the provided web-based CVS repository viewer.

To check out the latest version, simply type:
cvs co serious
To modify a module, you can't do it as an anonymous user, you need to be recorded as a developper and to have a password.
For the sourceforge user gorgoroth12 :
cvs -z3 co serious
The update, remove, commit, diff functions work as usual.
Please note that cedric baudry is currently the only developper who can commit his modifications, tell him if you also want to commit.

These setenv commands from my .tcshrc might be useful :
setenv CVS_RSH ssh
alias commit 'cvs commit -m "no message"'
alias sfimport 'cvs import -m "Initial import"'
alias sflogin 'cvs login'
alias sfco 'cvs -z3 co '
