Thanks.  Yeah, I discovered this the first time I tried setup.rb and
adjusted the directory structure accordingly so that data would end up
in /usr/share/sample/

Yup.  Actually, when I discussed this on irc, Paul van Tilburg
suggested:

http://svn.luon.net/filedetails.php?repname=goat&path=/trunk/lib/pre-setup.rb
http://svn.luon.net/filedetails.php?repname=goat&path=/trunk/lib/post-clean.rb

I like this approach.  This is what I envisioned people were doing
anyway.  I just was never able to find any examples of it being done
and was concerned about not reinventing the wheel.
