I couldn't agree more. I've been holding off until the Porter's Handbook
has clear documentation on what maintainers need to know. I've included
alepulver@ on this as he is the one that wrote the initial support for
this. I'd hate to see this grow into a mess that has to be cleaned up
later because there isn't proper documentation for maintainers.

Hopefully Alejandro has a PH update in the wings? If not then I guess
it's up to someone(TM) to do it.
