erwin.coumans 288df0df65 don't include cfloat by default, it breaks OSX and Linux build 2008-10-06 06:00:35 +00:00
erwin.coumans 2998d2a8f3 Added ReadBlend, a data extraction API for Blender's .blend files 
This can come in handy, to author physics data for Bullet from Blender, and directly get the physics data straight from the .blend file

Thanks a lot to Adam D. Moss, to digg up this code and make it available under the MIT license
It was mentioned several years ago in this thread:
