Vmex Source map decompiler

I have fun using Valve's Hammer map editing tool. But sometimes I am at a loss when it comes to how to make the level more interactive. That's where the vmex map decompiler comes in handy. I can find an example in an already compiled map, decompile it, and copy the parts I need. This is really useful if you want to create Portal maps, but don't want to screw around making super complex doors, ball launcher/catcher systems, or super-colliding-super-buttons. Here's a link to the Valve software wiki page.
