       advzip - AdvanceCOMP ZIP Compression Utility

       advzip [-a, --add] [-x, --extract] [-l, --list]
	    [-z, --recompress] [-t, --test] [-0, --shrink-store]
	    [-1, --shrink-fast] [-2, --shrink-normal] [-3, --shrink-extra]
	    [-4, --shrink-insane] [-N, --not-zip] [-p, --pedantic] [-q, --quiet]
	    [-h, --help] [-V, --version] ARCHIVES... [FILES...]
       The  main  purpose  of  this utility is to recompress and test the zip archives to get the
       smallest possible size.

       For recompression the 7-Zip (www.7-zip.com) Deflate implementation is used. This implemen-
       tation 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 compression than the 7-Zip Deflate implementation.

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

       -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 options are specified, it's
	      used the smallest file choice from: the previous compressed data, the new  compres-
	      sion  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.

       -N, --not-zip
	      Use the LZMA algorithm when compressing. The generated zips will not be readable by
	      any other application!

       -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  utili-

       -0, --shrink-store
	      Disable the compression. The file is only stored and not compressed. 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".

       -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".
