-// This is an example of a simple unit test to verify that the logic helper
-// functions works as expected.  Note that this looks like a 'normal' C++
-// program, with a main function.  It is compiled and linked using the NaCl
-// toolchain, so in order to run it, you must use 'sel_ldr_x86_32' or
-// 'sel_ldr_x86_64' from the toolchain's bin directory.
-//
-// For example (assuming the toolchain bin directory is in your path):
-//   sel_ldr_x86_32 test_helper_functions_x86_32_dbg.nexe
-//
-// You can also use the 'test32', or 'test64' SCons target to run these tests.
-// For example, this will run the test in 32-bit mode on Mac or Linux:
-//   ../scons test32
-// On Windows 64:
-//   ..\scons test64

-// A very simple macro to print 'passed' if boolean_expression is true and

-// choice.
