Quake BSP Texture Renamer v1.21 (c) 1998-2000 by Matthias Buecher
This was a "GL_LoadTexture: cache mismatch" workaround for OpenGL Quake/QuakeWorld.
The bug was fixed in the released sourcecode, but it still may be useful for map authors.
Included is a Quake BSP Texture Lister and BSP Texture Name Cleaner.
