+ * 
+ * When you want to test a module that is emulable on hosted
+ * platforms, these macros come in handy.
+ * Your module_test should supply three basic functions:
+ * 
+ * int module_testSetup(void)
+ * int module_testRun(void)
+ * int module_testTearDown(void)
+ * 
+ * All of these should return 0 if ok or a value != 0 on errors.
+ * 
+ * Then, at the end of your module_test you can write:
+ * #include TEST_ONLY(whatuneed.h)
+ * #include TEST_ONLY(whatuneed.c)
+ * #include TEST_ONLY(...)
+ * 
+ * TEST_MAIN(module);
+ * 
+ * The macro TEST_ONLY expand to nothing in non-TEST mode or to
+ * the specified filename if _TEST is defined.
+ * Including directly into your module the file.c you need to
+ * run the test allows you to build and run the test compiling
+ * only one file.
+ * 
+ * To achieve this you also need a main() that is supplied by
+ * the TEST_MAIN macro.
+ * This will expand to a full main that calls, in sequence:
+ * Setup, Run and TearDown of your module.
