Ever thought about learning a new programming language, doing your first try with a command line program, and first of all you want to have some command line options?
Maybe you have just an idea to do some difficult task in a small command line program, and of course you need options...
... but most of the time you have to reinvent the wheel?!
Why not using a small and easy library, which does exactly THAT task? Which gives you the possibility to fully concentrate on the original task to be done and developed?
In the end you can define your own commandline parameter style, because you define the option name yourself like 'CmdOptions.create("-myoption");' or '...create("+anotheropt")', etc.
The library - or better, the libraries - are planned to be consistent over all languages, so you are able to define and check and retrieve options with similar function calls.
