+// This is a system to schedule events into the emulated machine's future. Time is measured
+// in main CPU clock cycles.
+
+// To schedule an event, you first have to register its type. This is where you pass in the
+// callback. You then schedule events using the type id you get back.
+
+// See HW/SystemTimers.cpp for the main part of Dolphin's usage of this scheduler.
+
+// The int cyclesLate that the callbacks get is how many cycles late it was.
+// So to schedule a new event on a regular basis:
+// inside callback:
+//   ScheduleEvent(periodInCycles - cyclesLate, callback, "whatever")
