This script exports meshes to Raw Triangle file format.

The raw triangle format is very simple; it has no verts or faces lists.
It's just a simple ascii text file with the vertices of each triangle
listed on each line. There were some very old utilities (when the PovRay
forum was in existence on CompuServe) that preformed operations on these
files.

Usage:<br>
	Select meshes to be exported and run this script from "File->Export" menu.
