Beta version numbers

[Richard A Nelson <cowboy@vnet.ibm.com>]

I'm having trouble figuring out how to properly handle beta versions
without requiring an Epochs, or the inability to provide new source.

I've got sendmail-8.12.0.Beta5, but will eventually have sendmail-8.12.0-1.

 *) using sendmail-8.12.0-0Beta5 will allow 8.12.0-1 to superceed, but
    runs problems of replacing the .orig.tar.gz file

 *) using sendmail-8.12.0.Beta5 would need an epoch to have 8.12.0 superceed

What is the recommended approach to handle this?
