“Open Source Development with CVS” is a book from cvsbook.red-bean.com released under GNU GPL. I’ve been reading most of the CVS related capters, and it’s certainly a good start if you wish to use CVS. It’s a long book, and it takes you far beyond basic CVS commands. But it was also a good book, and for a person who has never used CVS before it was a good start. I can recommand it to anyone who wants to learn CVS, but you might want to skip a few capters, there’s a lot about develpment communities, which is not necessary to know if you just want to learn CVS. I feel a bit more confident using CVS for the next changes to P2PChat.
