+The BLAS (Basic Linear Algebra Subprograms) are high quality "building
+block" routines for performing basic vector and matrix operations. Level 1
+BLAS do vector-vector operations, Level 2 BLAS do matrix-vector operations,
+and Level 3 BLAS do matrix-matrix operations. Because the BLAS are
+efficient, portable, and widely available, they're commonly used in the
+development of high quality linear algebra software, LAPACK for
+example. This packages implements the reference FORTRAN 77 library,
+the reference C library as a wrapper to the FORTRAN 77 BLAS library.
+
+LAPACK is a comprehensive library that does linear algebra
+operations including matrix inversions, least squared solutions to
+linear sets of equations, eigenvector analysis, singular value
+decomposition, etc. It is a very comprehensive and reputable package
+that has found extensive use in the scientific community.
+This package installs the reference FORTRAN 77 implementation from Netlib.
