--  This package provides a thin binding to the standard Fortran BLAS library.
--  Documentation and a reference BLAS implementation is available from
--  ftp://ftp.netlib.org. The main purpose of this package is to facilitate
--  implementation of the Ada 2005 Ada.Numerics.Generic_Real_Arrays and
--  Ada.Numerics.Generic_Complex_Arrays packages. Bindings to other BLAS
--  routines may be added over time.
 
--  As actual linker arguments to link with the BLAS implementation differs
--  according to platform and chosen BLAS implementation, the linker arguments
--  are given in the body of this package. The body may need to be modified in
--  order to link with different BLAS implementations tuned to the specific
--  target.
