module Flutterby
  # NodeExtension is a subclass of Module that also provides a convenient
  # `setup` method for quick creation of initialization code. It's used
  # to wrap the blocks of code passed to {Node#extend_all} and friends,
  # but can also be used directly through `NodeExtension.new { ... }`.
  #
  class NodeExtension < Module
