A very simple, easy graphics file format.
Actually it is a whole family consisting of

"pbm" -> bitmap with depth=1, each pixel can be
         black/white (-> e.g. a typical Fax)
"pgm" -> a grayscale picture
"ppm" -> a RGB color picture (truecolor with RGB
         for each pixel, not with colormap/indexed
         like a GIF)
"pnm" -> used to denote the family, i.e. any of
         the above three

There also exist the pbmplus tools for manipulating
these file types, see /usr/X11R6/bin/*{pbm,pgm,ppm,pnm}*
