SUMMARY="An optimizer for PNG files"
DESCRIPTION="Pngcrush is an optimizer for PNG (Portable Network Graphics) \
files. It can be run from a commandline in an MSDOS window, or from a UNIX or \
LINUX commandline. Its main purpose is to reduce the size of the PNG IDAT \
datastream by trying various compression levels and PNG filter methods. It \
also can be used to remove unwanted ancillary chunks, or to add certain chunks \
including gAMA, tRNS, iCCP, and textual chunks."
