The game downloads the zipped file from the web server and then unzips it.

There is a program that automates the bzip and remote transfer from your server to your remote web host. It is very convenient, the only problem being that the library of non-map files is out of date due to all the various additions to the game. You can create a fresh copy from a fresh server installation, though.

I forget the name of the program but I will look it up when I can and I will also provide my own generated "do not upload" index file.
