 ML-Yacc parser generator.  Its class name is {\tt mlyacc}.  Recognized
 file name suffixes are {\tt .grm} and {\tt .y}.  For a source file
 $f$, the tool produces two targets $f${\tt .sig} and $f${\tt .sml},
-both of which are always treated as ML source files.  Parameters are
-passed on without change to the $f${\tt .sml} file but not to the
-$f${\tt .sig} file.

+Example\footnote{Since the generated {\tt .sig}-file contains nothing

 The tool invokes the {\tt ml-yacc} command if the targets are
