There is one additional point to bring up concerning Perl and CVS; the actual versioning itself. Perl's $VERSION variable assumes that version 5.101 is just a small update on 5.1 -- CVS believes that they are 100 revisions apart! Things get even more confusing when Perl claims that 5.2 is more recent than 5.101 This can lead to Wacky Hijinks^(tm) if you set the $VERSION variable in your program based directly on CVS' $Revision$ tag. You have been warned.
