+.Sh NAME
+.Nm lemon
+.Nd The Lemon Parser Generator
+.Sh SYNOPSIS
+.Nm
+.Op Fl bcgmqsx
+.Ar input
+.Sh DESCRIPTION
+.Nm
+is an LALR(1) parser generator for C or C++.
+It does the same job as bison and yacc.
+But 
+.Nm
+is not another bison or yacc clone.
+It uses a different grammar syntax which is designed to reduce the number of coding errors.
+.Nm
+also uses a more sophisticated parsing engine that is faster than yacc and bison
+and which is both reentrant and thread-safe.
+Furthermore, 
+.Nm
+implements features that can be used to eliminate resource leaks,
+making is suitable for use in long-running programs such as graphical user interfaces or embedded controllers.
+.Pp
+.Nm
+will read the grammer from
+.Ar input
+and write out a parser for that grammar in the C language.
+.Sh OPTIONS
+.Bl -tag -width indent
+.It Fl b
+Print only the basis in report.
+.It Fl c
+Don't compress the action table.
+.It Fl g
+Print grammar without actions.
+.It Fl m
+Output a makeheaders compatible file.
+.It Fl q
+(Quiet) Don't print the report file.
+.It Fl s
+Print parser stats to standard output.
+.It Fl x
+Print the version number.
+.El
+.Sh FILES
+.Bl -tag -width indent
+.It Pa /usr/share/lemon/lempar.c
+Driver template for the
+.Nm
+parser generator.
