At the risk of sounding dim, if you have variable files full of variable data, why don't you handle that logic in the ruby stanzas in your template? You can template the main file, and the ruby portions can write other files as needed. Otherwise, if you really have variable files full of variable data, I'm curious about just what application you're attempting to configure.
