From 283cc90566b42985069d5af0a92dbecb10675d0d Mon Sep 17 00:00:00 2001
From: Sean Dague
Date: Mon, 9 Jun 2008 18:24:07 +0000
Subject: start in on the shell for a generic database versioning module. My
intent is to create an easier way to manage database table versions like the
model used for ruby on rails migrations.
