SUMMARY="Pngcrush is an optimizer for PNG (Portable Network Graphics) 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."
