# Erubis template implementation. See:
# http://www.kuwata-lab.com/erubis/
#
# ErubisTemplate supports the following additional options, which are not
# passed down to the Erubis engine:
#
# :engine_class allows you to specify a custom engine class to use
# instead of the default (which is ::Erubis::Eruby).
#
# :escape_html when true, ::Erubis::EscapedEruby will be used as
# the engine class instead of the default. All content
# within <%= %> blocks will be automatically html escaped.
