+The Lemon  program is an  LALR(1) parser  generator. It takes  a context
+free grammar  and converts it into  a subroutine that will  parse a file
+using that grammar.
+
+Lemon is  similar to the much  more famous programs "YACC"  and "BISON".
+But lemon is not compatible with either yacc or bison. There are several
+important differences:
+
+	. Lemon using a different grammar  syntax which is less prone to
+	  programming errors.
+
+	. Lemon generates a parser that is faster than Yacc or Bison
+	  parsers (according to the author).
+
+	. The parser generated by Lemon is both re-entrant and thread-safe.
+
+	. Lemon includes the concept of a non-terminal destructor, which
+	  makes  it much  easier  to write  a parser  that  does not
+	  leak memory.
