NAME
       advdef - AdvanceCOMP Deflate Compression Utility

SYNOPSIS
       advdef [-z, --recompress] [-0, --shrink-store]
	    [-1, --shrink-fast] [-2, --shrink-normal] [-3, --shrink-extra]
	    [-4, --shrink-insane] [-i, --iter N]
	    [-f, --force] [-q, --quiet]
	    [-h, --help] [-V, --version] FILES...
DESCRIPTION
       The  main  purpose of this utility is to recompress the data present in
       the .png, .mng, .gz, .tgz and .svgz files.

       The internal structure of the files isn´t changed.  Only the compressed
       data is modified.

OPTIONS
       -z, --recompress FILES...
	      Recompress  the  specified  files. If the -1, -2, -3, -4 options
	      are specified it´s used the smallest file choice from the previ‐
	      ous 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  com‐
	      pressed. The file is always rewritten also if it´s bigger.

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

       -2, --shrink-normal
	      Set  the	compression level to "normal" using the 7z compressor.
	      This is the default level of compression.

       -3, --shrink-extra
	      Set the compression level to "extra" using  the  7z  compressor.
	      You  can	define	the  compressor iterations with the -i, --iter
	      option.

       -4, --shrink-insane
	      Set the compression level to "insane" using the zopfli  compres‐
	      sor.   You  can  define  the  compressor iterations with the -i,
	      --iter option.

       -i, --iter N
	      Define an additional numer of iterations for the 7z  and	zopfli
	      compressors for modes -3 and -4.	More iterations usually give a
	      better compression, but may require a lot more  time.   Try  for
	      example with 10, 15, 20, and so on.

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

LIMITATIONS
       The  advdef  program cannot be used to recompress huge files because it
       needs to allocate memory for both the complete  compressed  and	uncom‐
       pressed data.
