NAME

       pngchunkdesc - decode information embedded into a PNG chunk name

SYNOPSIS

        pngchunkdesc

DESCRIPTION

       PNGfiles  are  based  around  a  series of chunks, which embody the information stored in the image file.
       These chunks have  four  character  ASCII  names,  where  the  case  of  each  letter  stores  additional
       information.

       This  program  decodes  the case information in the chunk names, and displays it. The program reads chunk
       names from stdin, and write chunk descriptions to stdout.
