We have made Day of Defeat: Source available to preload. You can preload
it into a fresh location or with an existing Counter-Strike: Source or
Half-Life 2: Deathmatch installation.
Note that the preload does NOT give you a functional Day of Defeat:
Source server, the last little bit of the server (a couple MB worth)
will be released when the client is later today.
If you forget to put "-beta preload" on the command line then you will
not get the preload, so don't forget it.
