Project 1999 source?

[Sareil]

I am looking to contribute to p99, but first I want to get up to speed on eqemu. I've pulled the eqemu repo but I have read that p99 is a (probably slightly) modified version of eqemu and was wondering, where could I find those changes? I've looked around but no luck on the forums, and the wiki is decidedly lacking on dev info.

Thanks for the help on this.
