This directory contains the sources for the preprocessor portion of the
HAL  assembler for the Alpha family of products.  It represents PP Version 1.3.
It should contain the following files:

 README			This file
 Makefile		A unix-style makefile to compile pp

 avl.h			Source module
 avl_mod.c		Source module
 dir.c			Source module
 lexyy.h		Source module
 main.c			Source module
 memmgt.c		Source module
 pp.h			Source module
 sym.c			Source module
 utl.c			Source module

 lex.yy.c		This file has been generated by GNU flex version 2.3
			  from pp.l

 pp.output		
 pp.tab.c		
 pp.tab.h		These files have been generated by GNU Bison 
			  version 1.16 from pp.y

 pp.l			The lexical portion of the parser, input file to Flex
 pp.y			The grammar used for pp, input file to Bison


If it is necessary to compile the preprocessor and there is not an installed 
version of Flex or Bison, remove the appropriate lines from Makefile, and use
the outputs of Flex (lex.yy.c) and Bison (pp.tab.c, pp.tab.h) directly.

If a change must be made to pp.l or pp.y, and Flex or Bison do not exist,
the preprocessor cannot be recompiled.
