Hey, I just finished a Shell Script (with the other necessary files) that installs Tremulous, MacRadiant 1.5, and all of the necessary files to run a Tremulous server.
IT'S A MAC ONLY SCRIPT.
It also has individual installs for a server and one for mapping. And, of course, it comes with an uninstaller for each installer.
It comes with every file included (no additional downloads necessary, except Tremulous maps), and weighs in at 141.6 MB zipped. After unzipping, it comes to a total of 225.3 MB.
All you have to do to install it is drag "Install All MacTremFiles.sh" into Terminal.app and press Return. It won't overwrite any Tremulous files of your own, it will only ADD THE ONES YOU DON'T HAVE. It comes with 62 server commands.
The scripts have been tested many times (mostly results from my other projects--MacTremServ and MacTremMap, which were directly incorporated into this project). Take a look and let me know what features you want in the next version!
