If you're using a cvs snapshot from december 2004 or later, you can specify the config dir (the dir for user data) with the command line parameter --configdir. As the saved game location is inside that dir by default, that will also change the saved game location. A temporary hack from the same date also allows you to use environment variables UQM_CONFIG_DIR, UQM_SAVE_DIR, and UQM_MELEE_DIR, but this may be changed in the future.
