#  This program produces image files from color lists, in which the
#  image file contains one pixel for each color.  The image files are
#  16x16 pixels.  If a color list has less than 256 colors, the rest
#  of the image is black.  If the color list has more than 256 colors
#  only the first 256 are processed.
#
#  The image file names have the basename of the color list files followed
#  by _p and the suffix .gif.
