       The  main purpose of this utility is to recompress and test the zip ar‐
       chives to get the smallest possible size.

       For recompression the 7-Zip ( Deflate  implementation  is
       used.  This  implementation generally gives 5-10% more compression than
       the zLib Deflate implementation.

       For experimental purpose also the 7-Zip	LZMA  algorithm	 is  available
       with the -N option. In this case, the generated zips WILL NOT BE USABLE
       by any other program. To make them usable you need to  recompress  them
       without	the -N option. Generally this algorithm gives 10-20% more com‐
       pression than the 7-Zip Deflate implementation.

       -a, --add ARCHIVE FILES...
	      Create the specified archive with the specified files. You  must
	      specify only one archive.

       -x, --extract ARCHIVE
	      Extract all the files on the specified archive. You must specify
	      only one archive.

       -l, --list ARCHIVES...
	      List the content of the specified archives.

       -z, --recompress ARCHIVES...
	      Recompress the specified archives. If the -1, -2, -3, -4 options
	      are specified, it´s used the smallest file choice from: the pre‐
	      vious compressed data, the new compression and the  uncompressed
	      format.  If  the	-0  option  is specified the archive is always
	      rewritten without any compression.

       -t, --test ARCHIVES...
	      Test the specified archives. The tests may be extended with  the
	      -p option.

       -k, --keep-file-time
	      When recompressing with -z keep the .zip file time.

       -p, --pedantic
	      Be  pedantic on the zip tests. If this flag is enabled some more
	      extensive tests on the zip integrity are done. These  tests  are
	      generally not done by other zip utilities.

       -0, --shrink-store
	      Disable  the  compression.  The file is only stored and not com‐
	      pressed. This option is very useful to expand  the  archives  of
	      .png  and .mp3 files. These files are already compressed, trying
	      to compress them another time is really  a  waste	 of  time  and

       -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

       -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.
