Option++ is a C++ library for reading command-line program options. Option++ provides an easy way to read, validate, and process command-line arguments and it can also print detailed program help information.

A single-header version of the library is available. If you use the single-header file, you must define the macro OPTIONPP_MAIN in exactly one source file before including the header.
