DSL code to handle SASSC compiler options
(build <arachne-id> compiler-opts)
Define an Asset transducer component which builds SASSC. Arguments are: - arachne-id (optional): the Arachne ID of the component - compiler-options: A SASSC compiler options map. The only difference is that options which specify paths (:output-to, :output-dir,etc.) will relative to the asset fileset rather than the process as a whole. Returns the entity ID of the newly-created component.
