		// 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\half-life 2.

		SearchPaths
		{
			// First, mount all user customizations.  This will search for VPKs and subfolders
			// and mount them in alphabetical order.  The easiest way to distribute a mod is to
			// pack up the custom content into a VPK.  To "install" a mod, just drop it in this
			// folder.
			//
			// Note that this folder is scanned only when the game is booted.
			game+mod			hl2/custom/*

			// Now search loose files.  We'll set the directory containing the gameinfo.txt file
			// as the first "mod" search path (after any user customizations).  This is also the one
			// that's used when writing to the "mod" path.
			game+mod+mod_write+default_write_path		|gameinfo_path|.
			gamebin				|gameinfo_path|bin

			// We search VPK files before ordinary folders, because most files will be found in
			// VPK and we can avoid making thousands of file system calls to attempt to open files
			// in folders where they don't exist.  (Searching a VPK is much faster than making an operating
			// system call.)
