SCons: 1.0.0 is now available

SCons is a software construction tool (build tool, substitute for Make) implemented in Python, based on the winning design in the Software Carpentry build tool competition (in turn based on the Cons build tool).

Version 1.0.0 of SCons has been released and is now available at the
SCons download page:

    http://www.scons.org/download.php

RPM and Debian packages and a Win32 installer are all available, in
addition to the traditional .tar.gz and .zip files.

The SCons API available in release 1.0.0 is considered stable, and no
1.x release will knowingly break backwards compatibility with
SCons configuration files that work under 1.0.0. For further
information, please see our release planning criteria at:

WHAT'S NEW IN THIS RELEASE

This release is functionally equivalent to the 0.98.5 release
and contains only documentation updates.

IMPORTANT: Python versions prior to 2.2 are supported by SCons 1.0.0,
but are officially deprecated and will generate a disableable warning
message. We plan to remove support for these older versions in
SCons 2.0. If removing this support would cause a problem for you,
please contact the dev@scons.tigris.org mailing list.
