Developing a program, need directory names of games

[BR5DY]

I'm developing, and almost have completed, a server management utility that works with srcds.exe. I need to know the games' directory names. I found this list online, can anyone verify its accuracy? This is located in a subdirectory of srcds.exe.

Code:

(Game = Directory Name)
Age of Chivalry = ageofchivalry
Alien Swarm = alienswarm
Counter-Strike: Source = Counter-Strike Source
D.I.P.R.I.P. Warm Up = diprip
Day of Defeat Source = dods
Dystopia = dystopia
Eternal Silence = esmod
Garry's Mod = garrysmod
Half-Life 2 Deathmatch = hl2mp
Insurgency = insurgency
Left 4 Dead = left4dead
Left 4 Dead 2 = left4dead2
Pirates, Vikings and Knights II = pvkii
Synergy = synergy
Team Fortress 2 = tf
The Episide 1 engine for game mods = episode1
The Orange Box engine for game mods = orangebox
Zombie Panic! Source = zps

Thanks!
