Introducing Migrator

Just wanted to give a quick pointer to a script I just wrote. I always
hated having to give exact VERSION parameters to rake db:migrate:up/
down. So migrator is a simple command line tool which lets you enter
migration names instead of versions and invokes rake db:migrate:up/
down for you. It supports name completion and running migrations for
multiple environments.
