[Fedora-packaging] release tag question.

Hi.. Just looking at the cvsup package, as I need to use it at work. Anywho.. Just curious the rationale for the release tag. The actual version of the package is 16.1h, but its packaged as 16.1 and the "h" is pushed out into the release tag. Like: cvsup-16.1-9h Why? Would this not work: cvsup-16.1h-9 My first guess is that version comparisons would be messed up if the h was in the version tag, but then would it not mess up the release comparison also? Michael
