+//===-- Debug.cpp - An easy way to add debug output to your code ----------===//
+//
+// This file implements a handle way of adding debugging information to your
+// code, without it being enabled all of the time, and without having to add
+// command line options to enable it.
+//
+// In particular, just wrap your code with the DEBUG() macro, and it will be
+// enabled automatically if you specify '-debug' on the command-line.
+// Alternatively, you can also use the SET_DEBUG_TYPE("foo") macro to specify
+// that your debug code belongs to class "foo". Then, on the command line, you
+// can specify '-debug-only=foo' to enable JUST the debug information for the
+// foo class.
+//
+// When compiling in release mode, the -debug-* options and all code in DEBUG()
+// statements disappears, so it does not effect the runtime of the code.
+//
