[gentoo-pms] adding md5-cache to PMS

[Brian Harring]

Folks; as you're aware, md5-cache is now in use for gentoo-x86; I 
expect the people on this ml also understand the gains of it and why 
it effectively renders the existing PMS cache dead in the water.

The problem however is that it's not documented in PMS.  We need that 
documentation update.

Someone able to volunteer for this?  I specifically want it in EAPI5; 
there's no reason to leave it out.  If someone volunteers and has 
questions, I can answer anything in re: to it- same for any other PM 
author.

So... volunteers?
