blender/release/scripts/wings_export.py
Willian Padovani Germano 62147bba30 Scripts (making some changes to the scripts dir): 
- moved bpydata/ to scripts/bpydata/ and added a config/ subdir to it;
- created scripts/bpymodules for py modules (also got rid of those "mod_"'s appended to the files);
- updated scripts accordingly.

This will require you to "reinstall" (just copy the scripts/ dir over your older one) if you have a .blender/scripts/ dir somewhere.  Otherwise some scripts won't work.  You can use the updated "Help->System->System Information" script here to check all is fine.  An installer script yet to be written will help users with these issues, specially to make the user defined dir have the same structure expected from the default scripts dir, so the basic facilities (module search; saved config data; scripts: installer, help browser, config editor) are also available for a user's own collection of written and downloaded scripts.

BPython:
- slikdigit's crash was because he had no <home or blender exe location>/.blender/:
  proper check added and also now if all else fails the <cvsblender>/release/scripts/ dir is also searched for scripts.  All this registration dirs stuff is a little messy (installation!), so please report any troubles (I only tested on linux).
- slight change in error report in BPY_interface.c's BPY_menu_do_python; remembering to set globaldict pointer to NULL there, too.
- moved bpy_gethome() to EXPP_interface.[ch]
- "//" as user defined python dir is ignored while looking for scripts, considering it's only a default some users use, not really meant for a scripts dir.

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.
