++Module Creation Notes
++=====================
++
++For those creating tslib modules, it is important to note a couple things with
++regard to handling of the ability for a user to request more than one ts event
++at a time.  The first thing to note is that the lower layers may send up less
++events than the user requested, but only if that was a result of a pen release.
++Next, your module should send up just as many events as the user requested in
++nr.  If your module is one that consumes events, such as variance, then you
++loop on the read from the lower layers, and only send the events up when
++1) you have the number of events requested by the user, or 2) one of the events
++from the lower layers was a pen release.
