blender/release/scripts/wings_export.py
Willian Padovani Germano b970eadedf Scripts: 
- updating some bundled scripts, thanks to authors Jean-Michel Soler, Campbell Barton and Anthony D'Agostino.

BPython:
- removing wrong fix from BGL.c's glDrawPixels.

note: applied guitargeek's setName patch to Blender.Key, but saw that he updated it with more functionality and assigned to stivs, so I won't commit this old version.

This script exports meshes to Wings3D file format.
Wings3D is an open source polygon modeler written in Erlang, a
language similar to Lisp. The .wings file format is a binary
representation of erlang terms (lists, tuples, atoms, etc.) and is
compressed with zlib.
Usage:<br>
Select meshes to be exported and run this script from "File->Export" menu.
Supported:<br>
1. Exports meshes only. Hint: use ALT-C to convert non-mesh objects,
and CTRL-ALT-A if you have "dupliverts" objects.<br>
2. Exports Vertex Colors & Radiosity Solutions.
Missing:<br>
Materials and UV Coordinates info will be ignored.
Known issues:<br>
Exports only well-behaved and topologically correct meshes (i.e,
closed meshes, manifolds, meshes imported from wings, etc). The mesh
cannot have duplicate vertices, missing faces (holes), open edges, etc.<br>
PowerUser Hint: In editmode, if CTRL-ALT-SHIFT-M results in a selection,
then your mesh is not a manifold and most likely will not export.
Notes:<br>
Last tested with Wings 3D 0.98.25 & Blender 2.35a.
