blender/release/scripts/wings_export.py
Willian Padovani Germano b82be27659 Bundled scripts: 
-starting updates and new additions for Blender 2.34:
  Some of the new scripts require Python modules not builtin with Blender, so you either need a full Python install or the needed extra modules.  This is an ongoing work, there should be more scripts, better testing and also proper ways to tell users they don't have all expected modules.  It's expected that Win users won't need full Python installs, since we can provide a minimal zip with the needed modules from 2.34 on.

Thanks to Anthony D'Agostino (scorpius), Jean-Michel Soler (jms) and Campbell Barton (Cam / ideasman) for donating the scripts now added / updated.

BPython:
-added two new script menu groups: Tools and Utils.  We still need to find places elsewhere in the gui where the groups can be put.
