@ -36,6 +36,7 @@ The major CLI parsers for C++ include:
* [Cxxopts]: C++11, single file, and nice CMake support, but requires regex, therefore GCC 4.8 (CentOS 7 default) does not work. Syntax closely based on Boost PO, so not ideal but familiar.
* [DocOpt]: Completely different approach to program options in C++11, you write the docs and the interface is generated. Too fragile and specialized.
* [GFlags]: The Google Commandline Flags library. Uses macros heavily, and is limited in scope, missing things like subcommands. It provides a simple syntax and supports config files/env vars.
* [GetOpt]: Very limited C solution with long, convoluted syntax. Does not support much of anything, like help generation. Always available on UNIX, though (but in different flavors).
So, this library was designed to provide a great syntax, good compiler compatibility, and minimal installation fuss.
