# Liquid template implementation. See:
# http://liquid.rubyforge.org/
#
# Liquid is designed to be a *safe* template system and threfore
# 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.
#
# It's suggested that your program require 'liquid' at load
# time when using this template engine.
