Better Enums is a single, lightweight header file that makes your compiler generate reflective enum types.

That means you can easily convert enums to and from strings, validate them, and loop over them. In C++11, you can do it all at compile time.

It's what built-in enums ought to support. Better Enums simply adds the missing features. And, it is based on the best known techniques, thoroughly tested, fast, portable, and documented exhaustively.

To use it, just include enum.h and begin the tutorial!
