--- Comment required if non-RM package ???
+-- 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.
