Thank you, done, or at least I hope so

Is this process documented anywhere? Should it be? (It is in fact
relatively simple and a hello-world example could be added somewhere
to the wiki or the guide.)

OK, I will try to figure out how to convince Geant4 to link against that one.

You can either use "version 7.0-beta" and increase the revision when you want to grab a newer upstream, or you can invent specific version numbers, perhaps with the date, like "version 7.0-beta-20130723". Either way, if you ever update the port to "version 7.0", vercmp will consider that older, so you'll have to increase the epoch then to work around that.

Where is the "comparison algorithm" for vercmp documented (if
anywhere)? I will probably face the same problem with Geant4
transiting from 10.0.b01 -> 10.0 -> 10.0.p01 -> 10.0.p02 -> ... Maybe
there's a trick to invent a version that will keep increasing ;)
