+# This module produces the Metronome Architectural Protocol on top of Timer Library.\r
+#\r
+# This is a generic implementation of the Metronome Architectural Protocol that\r
+# layers on top of an instance of the Timer Library.  The Timer Library provides\r
+# functions for nanosecond and microsecond delays.  This generic implementation\r
+# produces a fixed TickPeriod of 100ns unit, and when the WaitForTick() service\r
+# is called, the number of ticks passed in is converted to either nanosecond or\r
+# microsecond units.  If the number of ticks is small, then nanoseconds are used.\r
+# If the number of ticks is large, then microseconds are used.  This prevents\r
+# overflows that could occur for long delays if only nanoseconds were used and also\r
+# provides the greatest accuracy for small delays. \r
