24fcfbe5fSBarry Smith   This file dispatches between various header files for blas/lapack distributions to handle the name mangling.
34fcfbe5fSBarry Smith   It also provides C prototypes for all the BLAS/LAPACK functions that PETSc uses
4*f3da1532SBarry Smith 
5*f3da1532SBarry Smith   This is not included automatically by petscsys.h because some external packages include their own prototypes for
6*f3da1532SBarry Smith   certain BLAS/LAPACK functions that conflict with the ones given here. Hence this should only be included when needed.
