		SteamAppId				550		// This will mount all the GCFs we need (240=CS:S, 220=HL2).
		ToolsAppId				563		// Tools will load this (ie: source SDK caches) to get things like materials\debug, materials\editor, etc.
		
		//
		// The code that loads this file automatically does a few things here:
		//
		// 1. For each "Game" search path, it adds a "GameBin" path, in <dir>\bin
		// 2. For each "Game" search path, it adds another "Game" path in front of it with _<langage> at the end.
		//    For example: c:\hl2\cstrike on a french machine would get a c:\hl2\cstrike_french path added to it.
		// 3. For the first "Game" search path, it adds a search path called "MOD".
		// 4. For the first "Game" search path, it adds a search path called "DEFAULT_WRITE_PATH".
		//

		//
		// Search paths are relative to the base directory, which is where hl2.exe is found.
		//
		// |gameinfo_path| points at the directory where gameinfo.txt is.
		// We always want to mount that directory relative to gameinfo.txt, so
		// people can mount stuff in c:\mymod, and the main game resources are in
		// someplace like c:\program files\valve\steam\steamapps\<username>\half-life 2.
