      advpng - AdvanceCOMP PNG Compression Utility

      :advpng [-l, --list] [-z, --recompress] [-0, --shrink-0]
      :     [-1, --shrink-fast] [-2, --shrink-normal [-3, --shrink-extra]
      :     [-4, --shrink-insane] [-f, --force] [-q, --quiet]
      :     [-h, --help] [-V, --version] FILES...

      The main purpose of this utility is to recompress png
      files to get the smallest possible size.

      Please note that this utility is not able to read
      a generic file. It's granted to be able to read only
      the files generated by the AdvanceMAME emulator.

      To compress the files this utility uses the following

      * Remove all ancillary chunks.
      * Concatenate all the IDAT chunks.
      * Use the 7zip Deflate implementation.

      -l, --list FILES...
            List the content of the specified files.

      -z, --recompress FILES...
            Recompress the specified files. If the -1, -2, -3
            options are specified it's used the smallest file
            choice from the previous compressed data and the
            new compression. If the -0 option is specified the
            file is always rewritten without any compression.

      -0, --shrink-store
            Disable the compression. The file is
            only stored and not compressed. The file is always
            rewritten also if it's bigger.

      -1, --shrink-fast
            Set the compression level to "fast".

      -2, --shrink-normal
            Set the compression level to "normal". This is the
            default level of compression.

      -3, --shrink-extra
            Set the compression level to "extra".

      -4, --shrink-insane
            Set the compression level to "insane".

      -f, --force
            Force the use of the new file also if it's bigger.
