'man portfile' appears to be the only documentation for it beyond the
source, though the docs there are short of verbose:

     rpm-vercomp versionA versionB
         Compare two RPM-format versions for equality.

This works like strcmp() in that it returns -1, 0, or 1 when versionA is
earlier, equal, or later than versionB.
