Consider merge with rust-argparse

Hi,

I think this module https://github.com/tailhook/rust-argparse as the same goal as your's.
Please consider a merge between both because I think a lot of module will emerged to handle cli args and that's not necessary a good thing for standardization.

cf : tailhook/rust-argparse#14

Thanks for the heads-up. I agree that duplicating functionality (and maintenance) across separate libraries should be avoided wherever possible.

In their current forms, cli.rs and rust-argparse provide the same bells and whistles. argparse by definition covers argument-parsing and the obvious derivatives thereof (e.g. help output). My intention with cli.rs is to provide a collection of functions that are useful when developing CLI programs. Hypothetically, this could include functionality not related to arg-parsing, such as additional exit status helpers or some mechanism to load and parse configuration files (e.g. a dotfile in the user's home directory).

Maybe we should add a disclaimer in the cli.rs README to point this out and link to other similar libraries like argparse. I don't want to go so far as to deprecate cli.rs right now, but I'd like potential consumers to be informed as to alternatives.

@evnm Ok I got it. Maybe a solution could be to rely on rust-argparse for arg parsing parts and to evolve cli.rs in a much higher level module which bundle some functionalities like parse conf .... and include arg parse in those functionalities.
