Please add license information

[dm0]

Could you please add license information to your project?

[mmateja]

Any update on this? Library look really simple and easy to use. That's exactly what I'm looking for but I don't know if I can use it in my projects.

I would also like to know what license this is released under.

I really would like to use this library, but I'm not going to unless license is added.

Try using this - https://github.com/Taywee/args

Does similar stuff, is much more robust and has MIT license.
