-This directory contains the Bison parser generator.
+This package contains the GNU Bison parser generator.
 
-See the file INSTALL for compilation and installation instructions.
-See the file doc/FAQ for frequently asked questions.
+* Installation
+** Build
+See the file INSTALL for generic compilation and installation
+instructions.
 
-It was once true that, when installing Bison on Sequent (or Pyramid?)
-systems, you had to be in the Berkeley universe.  This may no longer
-be true; we have no way to tell.
+Bison requires GNU m4 1.4.6 or later.  See:
 
-On VMS, you will probably have to create Makefile from Makefile.in by
-hand.  Remember to do `SET COMMAND BISON' to install the data in
-`BISON.CLD'.
+      ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
 
-VMS and MS-DOS builds are probably broken right now.  If you are able
-to build Bison on either platform and you need to make changes to do
-so, please submit those changes as a bug report.
+** Internationalization
+Bison supports two catalogues: one for Bison itself (i.e., for the
+maintainer-side parser generation), and one for the generated parsers
+(i.e., for the user-side parser execution).  The requirements between
+both differ: bison needs ngettext, the generated parsers do not.  To
+simplify the build system, neither are installed if ngettext is not
+supported, even if generated parsers could have been localized.  See
+http://lists.gnu.org/archive/html/bug-bison/2009-08/msg00006.html for
+more details.
 
-Send bug reports to bug-bison@gnu.org.  Please include the version
-number from `bison --version', and a complete, self-contained test
-case in each bug report.
+* Questions
+See the section FAQ in the documentation (doc/bison.info) for
+frequently asked questions.  The documentation is also available in
+PDF and HTML, provided you have a recent version of Texinfo installed:
+run "make pdf" or "make html".
 
-If you have questions about using Bison which the documentation does
-not answer, send mail to help-bison@gnu.org.
+If you have questions about using Bison and the documentation does
+not answer them, please send mail to <help-bison@gnu.org>.
 
+* Bug reports
+Please send bug reports to <bug-bison@gnu.org>.  Please include the
+version number from `bison --version', and a complete, self-contained
