12 Starting with Netpbm 10.3, pnmarith is obsolete. Use
13 pamarith(1)instead.

15 pamarith is backward compatible with pnmarith except where your input
16 images have different depths. pnmarith would convert the one with the
17 lesser depth to have the higher depth before doing the arithmetic.
18 With pamarith, you must do that step separately, using pgmtoppm.
