Just been going through, backing up my game files, demo recording, and screenshots for future reference, demop playback, and assorted experiments. I was wondering where, off hand, I might find the specific build number for a given copy of the client--I have 7-8 different ones around for playing back demos at different stages of the game, but the issue number I assign some are guesses based on the date of the files/features available. Could anyone tell me where I can find the build number for the client?
