/*
  This file dispatches between various header files for blas/lapack distributions to handle the name mangling.
  It also provides C prototypes for all the BLAS/LAPACK functions that PETSc uses

  This is not included automatically by petscsys.h because some external packages include their own prototypes for
  certain BLAS/LAPACK functions that conflict with the ones given here. Hence this should only be included when needed.
