How to open .gma files?

I didn’t know where else to post. This is gmod 13 related so I thought here’s the right place.

I just started with gmod 13 and want to know how to open gma files, because alot of addons don’t work (minor bugs) and i want to fix them.

Nevermind, the newest extractor is at the bottom of http://facepunch.com/threads/1173875

I think it’s better to ask the uploader to fix the addons by themselves…so that we don’t get many duplicated entries of ‘X addon’ and ‘X addon fixed’.

some addons aren’t really uploaded by the original creator. Just some tards uploading broken addons…
