  MPI_Pcontrol - Controls profiling

  Input Parameters:
+ level - Profiling level 
-  ... - other arguments (see notes)

  Notes:
  This routine provides a common interface for profiling control.  The
  interpretation of 'level' and any other arguments is left to the
  profiling library.  The intention is that a profiling library will 
  provide a replacement for this routine and define the interpretation
  of the parameters.
