GNU的词法/语法分析器bison源码

This directory contains the Bison parser generator.

See the file INSTALL for generic compilation and installation instructions.
See the file doc/FAQ for frequently asked questions.

Bison requires GNU m4 1.4.3 or later.  See:

ftp://ftp.gnu.org/gnu/m4/m4-1.4.3.tar.gz

Bison can work with pre-1.4.3 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 1.4.3 as the first step in trying to fix it.

Please send bug reports to <[e-mail]>.  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 <[e-mail]>.
