The "ideal guide" for writing CLI apps in Rust

[killercup]

In the first meeting, we discussed how to decide what to work on. One approach is writing an "ideal guide".

The basic idea is to write guides about how to write a CLI app in Rust, but not by describing how it works right now, but how we imagine it should work some time in the future.

@vitiral mentioned that the cookbook might be a good inspiration.

A concrete example for guides centered around writing CLI apps are the quicli docs.

One of the current goals of ergo is to rewrite the cookbook with zero non-ergo dependencies. I think this will be a useful exercise to see the scope of a crate like ergo. I'm thinking we could take a similar approach here.

Aim of this issue:
@killercup :

it should be a guide that introduces new users to rust while showing how frictionless writing a cli is and what rust has to offer

Since no work has started on this, let's close this and let its idea be reborn in other issues!
