</I>You may be interested in _get_new_version() and _get_new_release()
functions in Youri::Package::RPM::Updater code, and their associated
test suite:

</I>><i> Cool! I knew there had to be something like this, but couldn't be

</I>Same hint with is_newer() function in Youri::Check::Test::Updates:
