 This package contains the GNU Bison parser generator.
 
-See the file INSTALL for generic compilation and installation instructions.
+* Installation
+** Build
+See the file INSTALL for generic compilation and installation
+instructions.
 
+Bison requires GNU m4 1.4.6 or later.  See:
+
+      ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz
+
+** 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.
+
+* 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".
 
-Bison requires GNU m4 1.4.6 or later.  See:
-
-ftp://ftp.gnu.org/gnu/m4/m4-1.4.6.tar.gz

-Bison can work with pre-1.4.6 distributions of GNU m4 if they are
-sufficiently patched, but if you encounter a bug with an older
-distribution and report a bug we will probably suggest that you
-upgrade to 1.4.6 as the first step in trying to fix it.
