%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.

- 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.
