+		This test file compares the generated code size of similar functions between raw
+                COM interface pointers (|AddRef|ing and |Release|ing by hand) and |nsCOMPtr|s.
+
+		Function size results were determined by examining dissassembly of the generated code.
+		mXXX is the size of the generated code on the Macintosh.  wXXX is the size on Windows.
+		For these tests, all reasonable optimizations were enabled and exceptions were
+		disabled (just as we build for release).
+
+		The tests in this file explore more complicated functionality: assigning a pointer
+                to be reference counted into a [raw, nsCOMPtr] object using |QueryInterface|;
+		ensuring that it is |AddRef|ed and |Release|d appropriately; calling through the pointer
+		to a function supplied by the underlying COM interface.  The tests in this file expand
+		on the tests in "Test01.cpp" by adding |QueryInterface|.
+
+		Windows:
+			raw01									 52
+			nsCOMPtr							 63
+			raw										 66
+			nsCOMPtr*							 68
+
+		Macintosh:
+			nsCOMPtr							120 	(1.0000)
+			Raw01									128		(1.1429)	i.e., 14.29% bigger than nsCOMPtr
+			Raw00									144		(1.2000)
