This program implements the "HistEq" function from the xv color editor for pgm files. For most pictures, it enhances the contrast noticeably. The effect is that after processing, for each x between 0 and 100, x percent of the image will have a brightness of at most x percent.
The program needs the pbmplus libraries.
