Rsync and cvsup are solving somewhat different problems. You can use cvsup against a server to obtain the files by different CVS tag or by timestamp (the tag= and date= parameters in a supfile), whereas rsync can only copy a checked-out workarea or the CVS repo itself. Try comparing cvsup and rsync where cvsup in in CVS mode, not in checkout mode... -- -Chuck
