At SoftLab we use our own scanner and parser generators, ScannerMaker
and ParserMaker. ParserMaker is a LALR(1) parser generator, that
generates efficient parsers with automatic error
recovery. ScannerMaker generates scanners that integrate nicely with
ParserMaker parsers. A third tool, ListerMaker, handles error messages
(and other listings).


These tools are used for all our compilers and translators, and are
also available as separate products.
