Yes, they are all just libs, so we could make "pmds" be a sub-dir of the lib
folder. I prefer the shorter path myself, but if others want a multi-level
hierarchy it's no big deal.

For the other libs, I'm not sure we need to split them up, and I also think
that trying to divide them into categories - and what those categories should
be could - cause endless discussion. However, maybe I'm overly pessimistic... :-)
