Bash/Zsh auto completion script generation support.

[sureshg]

I am not sure if this makes sense for this library. So just wanted to get your opinion on providing an option to generate Bash/Zsh completion scripts for the arguments like in some other cli/flag libraries

Sounds like a great idea! Are you interested in implementing it?

I will look into this at the weekend, if help is still wanted @xenomachina

That would be very much appreciated!

I am on vacation for the next week, so I probably won't have a chance to look at any PRs until I get back.

Is there any updates?
