2   This file dispatches between various header files for blas/lapack distributions to handle the name mangling.
3   It also provides C prototypes for all the BLAS/LAPACK functions that PETSc uses
4 
5   This is not included automatically by petscsys.h because some external packages include their own prototypes for
6   certain BLAS/LAPACK functions that conflict with the ones given here. Hence this should only be included when needed.
