module Clevic

  # A subclass of Clevic::DefaultView is created by Clevic::Record
  # when the latter is included in a Sequel::Model
  # subclass.
  # 
  # The Clevic::DefaultView subclass knows how to:
  # - build a fairly sensible UI from the the ORM model metadata.
  # - create a UI definition using a class method called define_ui.
  #
  # See Clevic::ModelBuilder for an example.
