       ppmtopgm - convert a portable pixmap into a portable graymap

       ppmtopgm [ppmfile]

       Reads  a portable pixmap as input.  Produces a portable graymap as out‐
       put.  The quantization formula used is .299 r + .587 g + .114 b.

       Note that although there is a pgmtoppm program, it is not necessary for
       simple  conversions  from  pgm to ppm, because any ppm program can read
       pgm (and pbm ) files automagically.  pgmtoppm is for colorizing	a  pgm
       file.   Also,  see ppmtorgb3 for a different way of converting color to

       Cold-hearted orb that rules the night
       Removes the colors from our sight
       Red is gray, and yellow white
       But we decide which is right
       And which is a quantization error.
