  Log:
  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.
