This program exists only for backward compatibility.
Use pnmcolormap, which replaced it in January 2002.
One trivial difference between ppmtomap and pnmcolormap all is that if
the input is PBM or PGM, ppmtomap would produce PPM output, whereas
pnmcolormap all produces the same kind of output as the input. This
should not be very noticeable, though, as PBM and PGM images are usu-
ally usable anywhere a PPM image is.
