I believe on checkout you can always use the '-r' option to specify version. But note that is version of the file, not a version of crossfire. I have been adding tags each time I make a crossfire release, so if you check out with a tag value, you will a version as it was for some particular release. There may be other cvs options to check out based on date and other factors. I would look at the cvs man page for them all.
