Gets all the required SteamGuard files for Steam's account protection system. Doesn't matter where steam is installed, because this will find the files automatically! Magic.
In order to log into a Steam account from a new device without having to wait for 7 days in order to preform basic actions such as trading, just copy the SteamGuard files from a computer which has already waited 7 days.
Just run this application on the computer which has already waited and it will Zip them up for you. No need to wait 7 days anymore when switching computers.
And hey, maybe you could do some malicious stuff as well, who knows.
