+Cactus Code Thorn BLAS
+Author(s)    : Erik Schnetter
+Maintainer(s): Cactus team
+Licence      : ?
+--------------------------------------------------------------------------
+
+1. Purpose
+
+Distribute the Basic Linear Algebra Subroutines (BLAS); see
+<http://netlib.org/blas/>.
+
+
+
+From the web site:
+
+The BLAS (Basic Linear Algebra Subprograms) are routines that provide
+standard building blocks for performing basic vector and matrix
+operations.  The Level 1 BLAS perform scalar, vector and vector-vector
+operations, the Level 2 BLAS perform matrix-vector operations, and the
+Level 3 BLAS perform matrix-matrix operations.  Because the BLAS are
+efficient, portable, and widely available, they are commonly used in
+the development of high quality linear algebra software, LAPACK for
+example.
