A simple command line tool to watch file changes and run their matching ruby spec.

Retest is a small command-line tool to help you refactor code by watching a file change and running its matching spec. Designed to be dev-centric and project independent, it can be used on the fly as a throw away tool. No Gemfile updates, no commits to a repo or configuration files required to start refactoring. Works with every Ruby projects (at least that is the end goal).
