defmodule Etiquette do
  @moduledoc """
  Define packet specifications using [`Spec`](`Etiquette.Spec`).

  A packet consists of formatted data. Declaring a specification, it's possible to define the
  structure of a packet and the different forms it can take. In essence, a packet is a sequence of
  fields, so [`Etiquette.Spec`](`Etiquette.Spec`) can be used to import everything that is needed
  to create a specification:

    use Etiquette.Spec

  Once [`Etiquette.Spec`](`Etiquette.Spec`) is used, the macros
  [`packet`](`Etiquette.Spec.packet/3`) and [`field`](`Etiquette.Spec.field/3`) are
  imported.
