and noticed dos line endings in a bunch of files so ran dos2unix on everything in bullet2. Erwin, I noticed there are a few files that do not have license info in them, couple of quick examples are: btDefaultMotionState.h btHashMap.h btQuickprof.cpp could you take a look at add where needed? If you want I can give a list of files I think should get it added and or just add the standard one say the one in src/btBulletCollisionCommon.h Kent
