  # help: `add global sc for all NAME: COMMAND`
  # help:    It will add a shortcut that will execute the command we supply.
  # help:    In case we supply 'for all' then the shorcut will be available for everybody
  # help:    If 'global' or 'generic' supplied and in Master channel then the shortcut will be available in all Bot channels.
  # help:    If you want to use a shortcut as a inline shortcut inside a command you can do it by adding a $ fex: _!run tests $cust1_
  # help:    Example:
  # help:        _add shortcut for all Spanish account: code require 'iso/iban'; 10.times {puts ISO::IBAN.random('ES')}_
  # help:    Then to call this shortcut:
  # help:        _sc spanish account_
  # help:        _shortcut Spanish Account_
  # help:        _Spanish Account_
