Unparsing

We also generate formatters from grammar descriptions. Given the grammar of a language (in SDF) an ASF+SDF specification is generated that can be used as a default formatter for that language [19]. We adapt the generated ASF+SDF specification to the demands of the company in question and we use the ASF+SDF compiler to generate an efficient stand-alone unparser.
