description     PNG file optimizer
long_description \
        OptiPNG is a PNG optimizer that recompresses the image files to a \
        smaller size, without losing any information.  The idea has been \
        inspired from pngcrush (http://pmt.sourceforge.net/pngcrush), and \
        is explained in detail in the PNG-Tech article 'A guide to PNG \
        optimization'.  The implementation is carried forward in OptiPNG, \
        which offers a faster execution per trial, and a wider search space.
