%description
The ATLAS (Automatically Tuned Linear Algebra Software) project is an
ongoing research effort focusing on applying empirical techniques in
order to provide portable performance. At present, it provides C and
Fortran77 interfaces to a portably efficient BLAS implementation, as
well as a few routines from LAPACK.

The performance improvements in ATLAS are obtained largely via
compile-time optimizations and tend to be specific to a given hardware
configuration. In order to package ATLAS for Fedora some compromises
are necessary so that good performance can be obtained on a variety
of hardware. This set of ATLAS binary packages is therefore not
necessarily optimal for any specific hardware configuration.  However,
the source package can be used to compile customized ATLAS packages;
see the documentation for information.

%changelog
* Fri Sep  8 2006 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-11
- Rebuild for FC6.
- Remove outdated comments from spec file.

* Mon Feb 13 2006 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-10
- Rebuild for Fedora Extras 5.
- Add --noexecstack to compilation of assembly kernels. These were
  previously marked executable, which caused problems with selinux.

* Mon Dec 19 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-9
- Rebuild for gcc 4.1.

* Mon Oct 10 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-8
- Make all devel subpackages depend on their non-devel counterparts.
- Add /etc/ld.so.conf.d files for -sse and -3dnow, because they don't
  seem to get picked up automatically.

* Wed Oct 05 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-7
- Forgot to add the new patch to sources.

* Tue Oct 04 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-6
- Use new Debian patch, and enable shared libs (they previously failed
  to build on gcc 4).
- Minor updates to description and README.Fedora file.
- Fix buildroot name to match FE preferred form.
- Fixes for custom optimized builds.
- Add dist tag.

* Wed Sep 28 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-5
- fix files lists.

* Mon Sep 26 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-4
- generate library symlinks earlier for the benefit of later linking steps.

* Wed Sep 14 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-3
- Change lapack dependency to lapack-devel, and use lapack_pic.a for
  building liblapack.so.

* Wed Sep 14 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-2
- Add "bit" macro to correctly build on x86_64.

* Tue Aug 16 2005 Quentin Spencer <qspencer@users.sourceforge.net> 3.6.0-1
- Initial version.
