... Configuration The dictionary accepts one obligatory parameter - RULES, which has to be set to the file describing parsing rules and output recipes. ... Each non-empty line is either a comment (when started with '#' symbol), or a conversion rule, and in the latter case has to contain whitespace-separated pattern and output recipe. Currently, pattern has to match the _integer_ (one, two or more) number of input tokens; they will be replaced with a single one. ...
