Highly experimental CLI builder

Example

Adding CLI to ./app.ts:

#!/usr/bin/env deno run --unstable -A

import "https://deno.land/x/make_cli@0.0.1/mod.ts";

export function echo(option, longOption) {
  // @echo         Prints options to console
  // --option      Option description
  // --long-option Long option description
  console.log({ option, longOption });
}

Output of ./app.ts echo --help:

app.ts echo

Prints options to console

Options:
  --option       Option description
  --long-option  Long option description

Implementaion details

Commands are created from all exported functions of Deno.mainModule.
Options are parsed from the function signature.
Descriptions are parsed from comments inside the function.
ES2018 guarantees that comments inside of a function are always preserved.
