/*@C
   SlepcInitializeFortran - Routine that should be called from C after
   the call to SlepcInitialize() if one is using a C main program
   that calls Fortran routines that in turn call SLEPc routines.

   Collective on PETSC_COMM_WORLD

   Level: beginner

   Notes:
   SlepcInitializeFortran() initializes some of the default SLEPc variables
   for use in Fortran if a user's main program is written in C.  
   SlepcInitializeFortran() is NOT needed if a user's main
   program is written in Fortran; in this case, just calling
   SlepcInitialize() in the main (Fortran) program is sufficient.
