This package contains the GNU Bison parser generator. See the file INSTALL for generic compilation and installation instructions. 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. Please 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. If you have questions about using Bison and the documentation does not answer them, please send mail to <help-bison@gnu.org>. ----- Copyright (C) 1992, 1998, 1999, 2003, 2004, 2005, 2008 Free Software Foundation, Inc.
