This Prefab was included in the first prefab pack from
www.planetstarsiege.com/zhandri/

You have decided to download 'hanger' (it's supposed to be 'hangar'),
a prefab/building for Starsiege: Tribes, created by Omnipotent.

To install this prefab/building you must first have v1.2 (or later) of
The Mappers Mod' for Starsiege: Tribes installed. Simply extract the
volume (*.vol) & script (*.cs) files into the '*/Tribes/' directory,
(where * is the drive letter you installed Tribes to) keeping the
directory structure intact. Alternatively you could manually place them
into your '*/Tribes/mappers/prefabs/' directory.
