%changelog
* Mon Oct 29 2007 Alexey Tourbin <at@altlinux.ru> 3.7.11-alt5
- packaged static libraries (requested by Pavel A. Piminov);
  use e.g. "g77 -static test.f -lblas" for static linkage
- changed src.rpm packaging to keep separate upstream tarball

* Tue Jan 09 2007 Alexey Tourbin <at@altlinux.ru> 3.7.11-alt4
- backported bugfix for "complex C = A A' bug"
- backported fix for ilaenv.f which improves LAPACK performance

* Sun Dec 10 2006 Alexey Tourbin <at@altlinux.ru> 3.7.11-alt3
- compiled with -mfpmath=387 to fix LAPACK test suite on x86_64
- actually packaged README.ALT

* Fri Dec 08 2006 Alexey Tourbin <at@altlinux.ru> 3.7.11-alt2
- imported sources into git and built with gear
- removed PRM_OPT_FLAGS hack that broke SSE2
- enabled /usr/lib/sse2/libatlas.so.3 for i586
- libatlas.so.3, libblas.so.3: made some internal functions hidden
- packaged docs (atlas-doc package has postscript documentation)
- added README.ALT, which explains some performance issues

* Tue Jun 06 2006 Alexey Tourbin <at@altlinux.ru> 3.7.11-alt1
- initial revision, with debian fixes
- PII-optimized BLAS (for i586) yields three-fold improvement
  over plain fortran BLAS (matrix cross-product in R)
- SSE2-optimized /usr/lib/sse2/libatlas.so disabled by default
  because of segfaults (try to rebuild `--with sse2' and let me know)
- HAMMER64SSE2 for x86_64
