This is the version of awk described in "The AWK Programming Language",
by Al Aho, Brian Kernighan, and Peter Weinberger
(Addison-Wesley, 1988, ISBN 0-201-07981-X).

Changes, mostly bug fixes and occasional enhancements, are listed
in FIXES.  If you distribute this code further, please please please
distribute FIXES with it.  If you find errors, please report them
to bwk@bell-labs.com.  Thanks.

The program itself is created by
	make
which should produce a sequence of messages roughly like this:

	yacc -d awkgram.y

conflicts: 42 shift/reduce, 83 reduce/reduce
	mv y.tab.c ytab.c
	mv y.tab.h ytab.h
	cc -O -c ytab.c
	cc -O -c b.c
	cc -O -c main.c
	cc -O -c parse.c
	cc -O maketab.c -o maketab
	./maketab >proctab.c
	cc -O -c proctab.c
	cc -O -c tran.c
	cc -O -c lib.c
	cc -O -c run.c
	cc -O -c lex.c
	cc -O ytab.o b.o main.o parse.o proctab.o tran.o lib.o run.o lex.o -lm

This produces an executable a.out;  you will eventually
want to move this to some place like /usr/bin/awk.

If your system is does not have yacc or bison (the GNU
equivalent), you must compile the pieces manually.  We have
included yacc output in ytab.c and ytab.h, and backup copies in
case you overwrite them.

NOTE: This version uses ANSI C, as you should also.  We have
compiled this without any changes using gcc -Wall and/or local C
compilers on a variety of systems, but new systems or compilers
may raise some new complaint; reports of difficulties are
welcome.

This also compiles with Visual C++ 4.1 on Windows 95 and
presumably Windows NT, *if* you provide versions of popen and
pclose.  The file missing95.c contains do-nothing versions that
can be used to get started with.  It is too much trouble to
figure out how to make these work for real.

The version of malloc that comes with some systems is sometimes
astonishly slow.  If awk seems slow, you might try fixing that.
