Subject: Packaging voodoo to support same code version on multiple releases.

reprepro strictly follows the Debian package rule that two package
files which have the same name must have identical content.  Which is
fine, except when we want to support the same version of a package on
multiple releases of the same Debian-flavored operating system.

The usual hack for this is to add a release-specific tag to the end of
the version string.  The brute force way of doing this requires
modifying the source package for each release, but there's an obscure
hack which lets us augment the binary package versions directly.
