CHANGES
New upstream release
http://www.openblas.net/Changelog.txt

DESCRIPTION
OpenBLAS is an optimized BLAS library based on
GotoBLAS2 1.13 BSD version and further extended.
OpenBLAS is licensed under the 3-clause BSD license.

HOMEPAGE
http://www.openblas.net/

CYGWIN NOTES
1) As BLAS it is around 5-10 times faster than Netlib reference,
   included in the liblapack0 package.

2) No devel package is provided as liblapack-devel already provide
   the needed headers and import.
   Openblas is fully compatible with Netlib BLAS.

3) libopenblas consist of a single file
     /usr/bin/cygblas-0.dll
   that will precede in PATH the liblapack0
     /usr/lib/lapack/cygblas-0.dll
   and used instead. Removing libopenblas will restore the
   usage of Netlib BLAS

4) CPU architecture covered up to now

5) Built with a max number of 16 threads; it should be enough
   to fully utilize up a 8 core dual thread.
   The fixed max limit at build time is a upstream limitation,
   if you need more than 16 let me know.
