 * Work with standard types, simple custom types, and extendible to exotic types.
 * Permissively licenced.
  
-The major CLI parsers for C++ include:
-
-* [Boost Program Options]: A great library if you already depend on Boost, but its pre-C++11 syntax is really odd and setting up the correct call in the main function is poorly documented (and is nearly a page of code). A simple wrapper for the Boost library was originally developed, but was discarded as CLI11 became more powerful. The idea of capturing a value and setting it originated with Boost PO.
-* [The Lean Mean C++ Option Parser]: One header file is great, but the syntax is atrocious, in my opinion. It was quite impractical to wrap the syntax or to use in a complex project. It seems to handle standard parsing quite well.
-* [TCLAP]: The not-quite-standard command line parsing causes common shortcuts to fail. It also seems to be poorly supported, with only minimal bugfixes accepted. Header only, but in quite a few files. Has not managed to get enough support to move to GitHub yet. No subcommands. Produces wrapped values.
-* [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).

+| [ProgramOptions.hxx] | Intresting library, less powerful and no subcommands. |
+| [Args] | Also interesting, and supports subcommands. I like the optional-like design, but CLI11 is cleaner and provides direct value access, and is less verbose. |
+| [Argument Aggregator] | I'm a big fan of the [fmt] library, and the try-catch statement looks familiar.  :thumbsup: Doesn't seem to support subcommands. |
  
 None of these libraries fulfill all the above requirements. As you probably have already guessed, CLI11 does.
 So, this library was designed to provide a great syntax, good compiler compatibility, and minimal installation fuss.
