README:

This is GNU Awk 4.0.2. It is upwardly compatible with Brian Kernighan's
version of Unix awk.  It is almost completely compliant with the
2008 POSIX 1003.1 standard for awk. (See the note below about POSIX.)

This is a bug fix release. See NEWS and ChangeLog for details.

Work to be done is described briefly in the FUTURES file.  Changes in this
version are summarized in the NEWS file. Please read the LIMITATIONS file.

Read the file POSIX.STD for a discussion of issues where the standard
says one thing but gawk does something different.

To format the documentation with TeX, use at least version 2010-12-23.17
of texinfo.tex. There is a usable copy of texinfo.tex in the doc directory.

INSTALLATION:

Check whether there is a system-specific README file for your system under
the `README_d' directory.  If there's something there that you should
have read and didn't, and you bug me about it, I'm going to yell at you.

See the file INSTALL for installation instructions.

If you have neither bison nor yacc, use the awkgram.c file here.  It was
generated with bison, and has no proprietary code in it.  (Note that
modifying awkgram.y without bison or yacc will be difficult, at best.
You might want to get a copy of bison from the FSF too.)

If you have an MS-DOS, MS-Windows, or OS/2 system, use the stuff in the `pc'
directory.  Similarly, there is a separate directory for VMS.

Appendix B of ``GAWK: Effective Awk Programming'' discusses configuration
in detail. The configuration process is based on GNU Autoconf and
Automake.

After successful compilation, do `make check' to run the test suite.
There should be no output from the `cmp' invocations except in the
cases where there are small differences in floating point values, and
possibly in the case of strftime. Several of the tests ignore errors
on purpose; those are not a problem.  If there are other differences,
please investigate and report the problem.

PRINTING THE MANUAL

The `doc' directory contains a recent version of texinfo.tex, which will
be necessary for printing the manual.  Use `make dvi' to get a DVI file
from the manual. In the `doc' directory, use `make postscript' to get
PostScript versions of the manual, the man page, and the reference card.
Use `make pdf' to get PDF versions of the manuals, the man page and
the reference card.

BUG REPORTS AND FIXES (Un*x systems):

Please coordinate changes through Arnold Robbins. In particular, see
the section in the manual on reporting bugs. Note that comp.lang.awk
is about the worst place to post a gawk bug report. Please, use the
mechanisms outlined in the manual.

Email should be sent to bug-gawk@gnu.org.  This is now a separate mailing
list at GNU Central.  The advantage to using this address is that bug
reports are archived at GNU Central.
