If anyone is trying to do ImpactJS Development on a Mac OSX 10.8, I've written a tutorial to get you up and running. This doesn't use any 3rd party software such as WAMP but instead uses the built in web-server. I just went through this tonight so I figured I'd record my steps and save someone else the trouble.

The tutorial includes:
* Getting Apache Running
* Getting PHP Running - For Weltmeister
* Setting up aliases to your ImpactJS game directories so you can have them anywhere on your machine.
