Well, I've never known a collection of code shared across multiple
client applications with the specific intent of consolidating
functonality under a single framework to be called many other things
than a "library". It doesn't matter what address space it's in, it's a
library of reusable code, so I think the name stands up.

Sascha, this is awesome, BTW. I'm going to see if I can get PWM for
MX5x and MC13892 under this..
