               PNG (pronounced "ping") is a new bitmap format which is currently in
               development. Its creation is an attempt to give the graphics community an
               alternative to the shortcomings and misgivings found in most popular file
               formats. The current legal situation involving the GIF format may also have
               something to do with it too :-)
