LZMA is a general purporse compression algorithm designed by Igor
|
|
Pavlov as part of 7-Zip. 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.
