Header-only getopt for C++

Single-file, header-only library of a POSIX getopt workalike.

#include <getopt.hpp>

// command -v -o arg ...
int main(int argc, char** argv)
{
    cxx::getopt getopt;

    bool verbose = false;
    char const* output = "default";

    for (int opt; (opt = getopt(argc, argv, "vo:")) != -1; ) {
        switch (opt) {
          case 'v':
            verbose = true;
            break;

          case 'o':
            output = getopt.optarg;
            break;

          case '?':
            // Error
        }
    }

    argc -= getopt.optind;
    argv += getopt.optind;

    // Now you can access positional arguments: argv[0], ..., argv[argc - 1]
}
