#       DBLAS1 -- Double precision real BLAS routines
#       ZBLAS1 -- Double precision complex BLAS routines
#
#       CB1AUX -- Real BLAS routines called by complex routines
#       ZB1AUX -- D.P. real BLAS routines called by d.p. complex
#                 routines
#
#      ALLBLAS -- Auxiliary routines for Level 2 and 3 BLAS
#
#       SBLAS2 -- Single precision real BLAS2 routines
#       CBLAS2 -- Single precision complex BLAS2 routines
#       DBLAS2 -- Double precision real BLAS2 routines
