description         optimizer for PNG files
long_description \
   pngcrush reads in a PNG image, and writes it out again, with the optimum \
   filter_type and zlib_level.  It uses brute force (trying filter_type \
   none, and libpng adaptive filtering, with compression levels 3 and 9).  \
   It does the most time-consuming method last in case it turns out to be \
   the best. Optionally, it can remove unwanted chunks or add gAMA and sRGB \
   chunks.
