This implementation generally gives 5\(hy10% more compression than the zLib Deflate implementation. .PP For experimental purpose also the 7\(hyZip LZMA algorithm is available with the \(hyN 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 \(hyN option. Generally this algorithm gives 10\(hy20% more compression than the 7\(hyZip Deflate implementation. .SH OPTIONS .TP .B \(hya, \(hy\(hyadd ARCHIVE FILES... Create the specified archive with the specified files. You must specify only one archive. .TP .B \(hyx, \(hy\(hyextract ARCHIVE Extract all the files on the specified archive. You must specify only one archive. .TP .B \(hyl, \(hy\(hylist ARCHIVES... List the content of the specified archives. .TP .B \(hyz, \(hy\(hyrecompress ARCHIVES... Recompress the specified archives. If the \(hy1, \(hy2, \(hy3 options are specified, it\(cqs used the smallest file choice from: the previous compressed data, the new compression and the uncompressed format. If the \(hy0 option is specified the archive is always rewritten without any compression. .TP .B \(hyt, \(hy\(hytest ARCHIVES... Test the specified archives. The tests may be extended with the \(hyp option. .TP .B \(hyN, \(hy\(hynot\(hyzip Use the LZMA algorithm when compressing. The generated zips will not be readable by any other application! .TP .B \(hyp, \(hy\(hypedantic 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. .TP .B \(hy0, \(hy\(hyshrink\(hystore 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 resource. .TP .B \(hy1, \(hy\(hyshrink\(hyfast Set the compression level to \(a"fast\(a". .TP .B \(hy2, \(hy\(hyshrink\(hynormal Set the compression level to \(a"normal\(a". This is the default level of compression. .TP .B \(hy3, \(hy\(hyshrink\(hyextra Set the compression level to \(a"extra\(a". .TP .B \(hy4, \(hy\(hyshrink\(hyinsane Set the compression level to \(a"insane\(a". .SH COPYRIGHT This file is Copyright (C) 2002 Andrea Mazzoleni, Filipe Estima .SH SEE ALSO advpng(1), advmng(1), advdef(1)
