+.SH NOTES FOR FORTRAN
+All MPI routines in Fortran (except for 
+.I MPI_WTIME
+and 
+.I MPI_WTICK
+) have
+an additional argument 
+.I ierr
+at the end of the argument list.  
+.I ierr
+is an integer and has the same meaning as the return value of the routine
+in C.  In Fortran, MPI routines are subroutines, and are invoked with the
+.I call
+statement.
+
+All MPI objects (e.g., 
+.I MPI_Datatype
+, 
+.I MPI_Comm
+) are of type 
+.I INTEGER
+in Fortran.
