I currently use two computers, one is windows 7 and mainly for gaming, and the other is running 11.10, when i was on Steam browsing today i noticed that at the bottom of the steam page you can click on a drop-down named "tools" and under it it says "Linux HLDS update tool" clicking on it brings up a download.

Does anyone know what this is for? Is this a patch for a Steam-Linux application that i am unaware of?
