+Catch stands for C++ Automated Test Cases in Headers and is a
+multi-paradigm automated test framework for C++ and Objective-C
+(and, maybe, C). It is implemented entirely in a set of header
+files, but is packaged up as a single header for extra convenience.
+
+Key features:
+
+ - Really easy to get started. Just download catch.hpp,
+ #include it and you're away.
+ - No external dependencies. As long as you can compile
+ C++98 and have a C++ standard library available.
+ - Write test cases as, self-registering, functions or
+ methods.
+ - Divide test cases into sections, each of which is run
+ in isolation (eliminates the need for fixtures!)
+ - Use BDD-style Given-When-Then sections as well as
+ traditional unit test cases.
+ - Only one core assertion macro for comparisons.
+ Standard C/C++ operators are used for the comparison -
+ yet the full expression is decomposed and lhs and rhs
+ values are logged.
