%description
    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.
