Ha! It seems like the obvious name if you're going to write a helper application for Jekyll. Most of the things I saw poking around were to generate scaffolding, which Jekyll can do by itself now.
I was annoyed with manually moving files around, so obviously the solution was to spend many more hours than I ever would have spent doing that writing this instead.
But kudos to the OP for delivering. I switched over to Middleman, so mine will never be publicly released.
