Which joint library should I use?

[jiandingzhe]

In the tutorial code, it refers to "dCustomJoints" library, which is given in the "packages" dir of the source dist (those returns "NewtonUserJoint").
However, there seems have another joints system which is mentioned in the online documentation (those returns "NewtonJoint").

Why there are two joint libraries? Which one should I use?

NetwonJoint is the inrface to the engine upon all joint are created.

In the early day, ther were some intenal libraries in teh engine, but that rqures too much maintance, and were abandone
station with 2.0 we have the dJointLibrary, that is the library you should use.
