It provides high compression ratio while +keeping the decompression speed fast. + +XZ Utils are an attempt to make LZMA compression easy to use on +free (as in freedom) operating systems. This is achieved by providing +tools and libraries which are similar to use than the equivalents +of the most popular existing compression algorithms. + +XZ Utils consist of a few relatively separate parts: + * liblzma is an encoder/decoder library with support for several + filters (algorithm implementations). The primary filter is + LZMA. + * libzfile (or whatever the name will be) enables reading from + and writing to gzip, bzip2 and LZMA compressed and uncompressed + files with an API similar to the standard ANSI-C file I/O. + [ NOTE: libzfile is not implemented yet. ] + * xz command line tool has almost identical syntax than gzip + and bzip2. It makes LZMA easy for average users, but also + provides advanced options to finetune the compression settings. + * A few shell scripts make diffing and grepping LZMA compressed + files easy. The scripts were adapted from gzip and bzip2. |
