Here's a little eclass I wrote the other day while out duck hunting
with a judge:

http://dev.gentoo.org/~ciaranm/tmp/versionator.eclass

The idea is to make it easier for people to get rid of a load of those
nasty global scope sed / cut calls. Actually, I lied. The idea is to
stop people from pestering me at 3am asking how to replace the second
hyphen with an underscore.

You could, of course, write a load of bash voodoo like certain ebuilds
do already. This leads to headaches though, especially when people get
it wrong...

Any use? Worth committing? I've got a few things that currently do bash
magic that could be converted over for readability purposes, and I know
others are in a similar situation...

Suggestions welcomed, especially if they come with patches.
