PATCHes followup, new dist dir to support packaging

[Jeffrey Blank]

Hello all,
In keeping with the goal of Shawn's recent patch submissions, I added a 
"dist" directory and placed some of the new information there.  This 
should put us on a patch to providing an RPM form of our output (and the 
directories there should clarify our goals as well).

Note that the files in the "output" directory are not necessarily final 
output, and at this time some of the scripts assume that they live in a 
flat directory.  The files in output may be further transformed (or may 
in fact be final output).  Lifting from "output" into "dist" shoud 
signify an intent to distribute as final product.

Thanks,
Jeff
