That, and a motivation/design-comparison with catch. From the readme, and a quick look - I couldn't really tell how this improves on catch, except for compile times (presumably mostly in the case where the lib generates main, as factoring this out is recommended for catch).

[ed: catch provides both bdd and tdd forms of tests, while this doesn't help lift comments up to the level of tests, unlike its python inspiration - which is understandable, but a bit confusing, given the name.]

[ed2: for an intro to catch, see eg: "CppCon 2015: Phil Nash “Test Driven C++ with Catch": https://m.youtube.com/watch?v=gdzP3pAC6UI ]
