module Tilt
  # Liquid template implementation. See:
  # http://liquidmarkup.org/
  #
  # Liquid is designed to be a *safe* template system and therefore
  # does not provide direct access to execuatable scopes. In order to
  # support a +scope+, the +scope+ must be able to represent itself
  # as a hash by responding to #to_h. If the +scope+ does not respond
  # to #to_h it will be ignored.
  #
  # LiquidTemplate does not support yield blocks.
