FreeSpace Open Installer
From FreeSpace Wiki
NOTE: The recommended launcher and installer for FreeSpace Open is now the Knossos (link here). The Freespace Open Installer is no longer the recommended launcher.
The FreeSpace Open Installer is an online installer for FS2_Open. The Installer was originally written by Turey, and then completely rewritten by Goober5000. The source code is hosted by the SCP.
The program's web page is here.
Instructions on creating an install.txt file are here. These are only for modders who are ready to add their released mod or campaign to the installer's list of available mods to install.
A mirror monitor for the various mods can be found here.
