[Bf-committers] New Developer Meeting minutes

[Erwin Coumans]

Bummer iPhone automatic spelling fixer ;)

It should be fixed I think. It works fine in our Bullet library.

New developers (and myself) can browse and debug code much easier in  
an IDE such as msvc, Xcode or K develop, in my opinion. And manual  
updating projectfiles is a waste of time.

Thanks,
Erwin
