Make a Gmod Config for Source SDK

How do I make a Gmod Config for Source SDK? I’m trying to get EP2 and CSS Stuff in it.

I followed this guide: http://wiki.garrysmod.com/?title=Configuring_Hammer , But I only get the HL2 and Gmod stuff.

HALP

Garrysmod configuration doesn’t load EP2 and CS:S, you have to extract the content from the GCF’s manually.

lame, I guess I can move my css stuff to ep2
