+// Monte Carlo: Estimate Pi
+// ========================
+//
+// This sample demonstrates a very simple Monte Carlo estimation for Pi.
+//
+// This file, main.cpp, contains the setup information to run the test, for
+// example parsing the command line and integrating this sample with the
+// samples framework. As such it is perhaps less interesting than the guts of
+// the sample. Readers wishing to skip the clutter are advised to skip straight
+// to Test.operator() in test.cpp.
