trunk/Rakefile

[Rocco Stanzione]

I created a Rakefile (sort of Ruby's version of a Makefile) in trunk, with the 
idea of consolidating some existing utilities (like building and validating) 
into one place, and possibly adding some new ones.  If anyone has suggestions 
for new utilities, ways to improve the existing ones, etc., I'd love to hear 
them.  Conversely, if anyone things it's a bad idea and it should go away, 
I'd like to hear those arguments too.

Thanks,
