               The Debian GNU Compiler Collection setup
               ========================================

Please see the README.Debian in /usr/share/doc/gcc, contained in the
gcc package for a description of the setup of the different compiler
versions.

For general discussion about the Debian toolchain (GCC, glibc, binutils)
please use the mailing list debian-toolchain@lists.debian.org; for GCC
specific things, please use debian-gcc@lists.debian.org.  When in doubt
use the debian-toolchain ML.

-----------------------------

Matthias Klose <doko@debian.org>
Ludovic Brenta <ludovic@ludovic-brenta.org>	(gnat)
