+  ATLAS is an approach for the automatic generation and optimization of
+  numerical software. Currently ATLAS supplies optimized versions for the
+  complete set of linear algebra kernels known as the Basic Linear Algebra
+  Subroutines (BLAS) for both c and F77 interfaces. It can also build
+  a subset of the linear algebra routine LAPACK library or the full
+  LAPACK using the reference LAPACK from Netlib.
