    // environment is always on if the 'env' option below is specified
  },
  alias: 'f', // shorthand console argument name
  env: 'foo_env', // name of the environment variable to read from
  message: 'input foo', // message to display in interactive prompt
  error: 'failed to read foo', // message to display when input was invalid
  error_callback: (opt, val, err)=>{...}, // function to call when an option value could not be read

#include base.json
{
  "foo": "bar"
