    longDescription = ''
      Library for sparse matrix computations featuring the Recursive Sparse
      Blocks (RSB) matrix format. This format allows cache efficient and
      multi-threaded (that is, shared memory parallel) operations on large
      sparse matrices.
      librsb implements the Sparse BLAS standard, as specified in the BLAS
      Forum documents.
      Contains libraries and header files for developing applications that
      want to make use of librsb.
