 * CHECK_FALSE(condition) - checks any boolean result
 * CHECK_FALSE_TEXT(condition, text) - checks any boolean result and prints text on failure.
 * CHECK_EQUAL(expected, actual) - checks for equality between entities using ==. So if you have a class that supports operator==() you can use this macro to compare two instances.  You will also need to add a StringFrom() function like those found in SimpleString. This is for printing the objects when the check failed.
+* CHECK_COMPARE(first, relop, second) - checks thats a relational operator holds between two entities. On failure, prints what both operands evaluate to.
 * CHECK_THROWS(expected_exception, expression) - checks if expression throws expected_exception (e.g. std::exception). CHECK_THROWS is only available if CppUTest is built with the Standard C++ Library (default).
 * STRCMP_EQUAL(expected, actual) - checks const char* strings for equality using strcmp().
 * STRNCMP_EQUAL(expected, actual, length) - checks const char* strings for equality using strncmp().
