A replacement for "livereload" gem on OS X

This script is a replacement for livereload server component designed for working with Rails. It watches the filesystem with FS Events (Mac OS X) rather than with EventMachine. This is better for large projects for wich EventMachine fails with "too many open files" exception.

Sass is supported; .sass files can also be stored in "app/styles/" directory. Compass is detected if "config/compass.rb" file exists.

Installation:

Download this script to somewhere in your PATH and make it executable. You can name it something different than "livereload" if you want to try this and the official gem executable in parallel.

UPDATE: Please see some of the forks for an updated version of this guide. I
myself have moved onto the Rails 3.1 betas to get the asset pipeline. But if
you want to stay on stable there are other folks who are keeping this guide
relevant despite the changes constantly occurring on Sprockets 2. The comments
on this gist will lead you to the right forks. :)

Some brief instructions on how to use Sprocket 2 in Rails to get CoffeeScript
powered JS and SASS powered CSS with YUI compression all via the magic of rack.

This stuff will be native in Rails 3.1 and the layout of the files on the

Implementation of the Luhn 10 algorithm to check validity of credit card numbers. See http://en.wikipedia.org/wiki/Luhn_algorithm for details on the algorithm.
