+/** @defgroup drawstuff DrawStuff
+
+DrawStuff is a library for rendering simple 3D objects in a virtual 
+environment, for the purposes of demonstrating the features of ODE.
+It is provided for demonstration purposes and is not intended for
+production use.
+
+@section Notes
+
+In the virtual world, the z axis is "up" and z=0 is the floor.
+
+The user is able to click+drag in the main window to move the camera:
+  * left button - pan and tilt.
+  * right button - forward and sideways.
+  * left + right button (or middle button) - sideways and up.

+ * @defgroup collide Collision Detection
+ *
+ * ODE has two main components: a dynamics simulation engine and a collision
+ * detection engine. The collision engine is given information about the
+ * shape of each body. At each time step it figures out which bodies touch
+ * each other and passes the resulting contact point information to the user.
+ * The user in turn creates contact joints between bodies.
+ *
+ * Using ODE's collision detection is optional - an alternative collision
+ * detection system can be used as long as it can supply the right kinds of
+ * contact information.

+ *
+ * Here is how it is done: after every time step linear and angular

+ * You can also limit the maximum angular velocity. In contrast to the damping
+ * functions, the angular velocity is affected before the body is moved.
+ * This means that it will introduce errors in joints that are forcing the body
+ * to rotate too fast. Some bodies have naturally high angular velocities
+ * (like cars' wheels), so you may want to give them a very high (like the default,
+ * dInfinity) limit.
+ *
+ * @note The velocities are damped after the stepper function has moved the

+ * @defgroup joints Joints
+ *
+ * In real life a joint is something like a hinge, that is used to connect two
+ * objects.
+ * In ODE a joint is very similar: It is a relationship that is enforced between
+ * two bodies so that they can only have certain positions and orientations
+ * relative to each other.
+ * This relationship is called a constraint -- the words joint and
+ * constraint are often used interchangeably.
+ *
+ * A joint has a set of parameters that can be set. These include:
+ *
+ *
+ * \li  dParamLoStop Low stop angle or position. Setting this to
+ *	-dInfinity (the default value) turns off the low stop.
+ *	For rotational joints, this stop must be greater than -pi to be
+ *	effective.
+ * \li  dParamHiStop High stop angle or position. Setting this to
+ *	dInfinity (the default value) turns off the high stop.
+ *	For rotational joints, this stop must be less than pi to be
+ *	effective.
+ *	If the high stop is less than the low stop then both stops will
+ *	be ineffective.
+ * \li  dParamVel Desired motor velocity (this will be an angular or
+ *	linear velocity).
+ * \li  dParamFMax The maximum force or torque that the motor will use to
+ *	achieve the desired velocity.
+ *	This must always be greater than or equal to zero.
+ *	Setting this to zero (the default value) turns off the motor.
+ * \li  dParamFudgeFactor The current joint stop/motor implementation has
+ *	a small problem:
+ *	when the joint is at one stop and the motor is set to move it away
+ *	from the stop, too much force may be applied for one time step,
+ *	causing a ``jumping'' motion.
+ *	This fudge factor is used to scale this excess force.
+ *	It should have a value between zero and one (the default value).
+ *	If the jumping motion is too visible in a joint, the value can be
+ *	reduced.
+ *	Making this value too small can prevent the motor from being able to
+ *	move the joint away from a stop.
+ * \li  dParamBounce The bouncyness of the stops.
+ *	This is a restitution parameter in the range 0..1.
+ *	0 means the stops are not bouncy at all, 1 means maximum bouncyness.
