This disk contains TP Lex and Yacc, compiler generator tools for Borland's
Turbo Pascal (4.0 or later), running under MS-DOS (3.0 or later).

(Turbo Pascal is a trademark of Borland International.)

The TP Lex and Yacc software is licensed free of charge and may be copied
and redistributed for non-profit purposes. There is no warranty of any kind.
In particular, I do not guarantee that the software is free of bugs, or fits
some particular purpose, and I take no responsibility for damages or any
other consequences of its use.

The manual is contained in the file TPLY.DOC on the disk. It can be printed
using the DOS command `copy tply.doc prn'. (A TeX'ed version of the manual
is contained in the file TPLY.TEX.) The manual provides a rather terse
description of TP Lex and Yacc and you should follow the references given
there for further reading.

As distributed, the TP Lex and Yacc library units (LEXLIB.TPU and
YACCLIB.TPU) are compiled with Turbo Pascal 6.0; to use them with other
Turbo Pascal versions you probably have to recompile these units (sources
LEXLIB.PAS and YACCLIB.PAS on the distribution disk).

Older versions of TP Lex and Yacc are no longer supported. Most programs
written for TP Lex and Yacc 2.0 should not to be too difficult to adapt
to the new version. The major differences are:

- The TP Lex library routine `start' is now used to set the start state of
  the lexical analyzer (in V2.0, this routine was named `begin_').

- TP Lex no longer supports character tables (%T).

- TP Lex now provides an optimization option which causes TP Lex to generate
  minimal DFA's, and a verbose option to generate a readable description
  (.LST file) of the constructed DFA.

- The TP Yacc error message printing routine is now named `yyerror' (as in
  the UNIX version); in V2.0 it was named `yymsg'. The V2.0 routine named
  `yyerror' (which t
