%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 an 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.
