I've started using CVS for DataVision. To browse the latest source via the Web or grab your own copy whenever you want, visit <http://sourceforge.net/cvs/?group_id=33343>. The only "modulename" you will need is "datavision".
When you're surfing the sources via the web, I noticed that clicking on the file name does not display the contents, it displays the CVS revision history. Click on the "Rev" link (the revision number) to the right of the file name to see the current source.
