This is a module with functions for handling mac addresses. There are already two or three MAC addressing functions in CPAN, the motivation for this module is moderate functionality without Moose.
With that in mind, you can understand why I have cloned much of the really useful functionality from the two or three existing similar modules on CPAN.
I've covered off all the mac address formats I deal with in my workplace of mixed hardware. This module can decode just about anything that looks reasonably like a mac address, and stringify into every format I have seen used...
So sorry, I'm not really interesting in adding a templating function to define your own mac address formats. You're welcome to either send in a patch, extend this module or quickly write a function that wraps the 'raw' output to whatever you want. Match and join are your friends :)
Hopefully this module is useful to you. So far I have been pleased with the amount of feedback and patches people have sent in, this has been very rewarding as well as providing a number of new features I have been able to use myself.
