  #
  # Output classes know how to write rendered node data to an output location.
  #
  # An output class must respond to three methods
  #
  # <tt>exists?(path)</tt>::
  #   Return +true+ if the output path exists.
  # <tt>delete(path)</tt>::
  #   Delete the given output path.
  # <tt>write(path, data, type)</tt>::
  #   Write the data to the given output path. The parameter +type+ specifies the type of the
  #   to be written path: <tt>:file</tt> or <tt>:directory</tt>.
  # <tt>read(path)</tt>:
  #   Return the content of the given path if it exists or raise an error otherwise.
