CVS allows the code of a project to be managed so that a group of people can work safely on a single project from different locations. If you would like to access the latest versions of libraries or projects we have online you will need to setup a CVS client. I use wincvs which provides a very simple to use windows client. You can get it here. To access the repository anonymously you will need to use the following setup.
CVSROOT: :pserver:anonymous@ps2dev.org:/home/ps2cvs
PASSWORD: anonymous
If you would like to view the repository online you can select here. To put your own project online you will need to get an account with write access to the repository. Please email me, or post a message to a forum.
