 | [ProgramOptions.hxx] | Intresting library, less powerful and no subcommands. Nice callback system. |
 | [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. |
+| [Clara] | Simple library built for the excellent [Catch] testing framework. Unique syntax, limited scope. |
