CLI11 - a command line parser for C++11 and beyond

CLI11 provides all the features you expect in a powerful command line
parser, with a beautiful, minimal syntax and no dependencies beyond
C++11. It is header only, and comes in a single file form for easy
inclusion in projects. It is easy to use for small projects, but
powerful enough for complex command line projects, and can be
customized for frameworks.
