+%description
+XZ provides very high compression ratio and fast decompression. The
+core of the XZ utils is Igor Pavlov's LZMA SDK containing the actual
+LZMA encoder/decoder. LZMA utils add a few scripts which provide
+gzip-like command line interface and a couple of other XZ related
+tools. Also provides:
+
+- Average compression ratio 30% better than that of gzip and 15%
+  better than that of bzip2.
+
+- Decompression speed is only little slower than that of gzip, being
+  two to five times faster than bzip2.
+
+- In fast mode, compresses faster than bzip2 with a comparable
+  compression ratio.
+
+- Achieving the best compression ratios takes four to even twelve
+  times longer than with bzip2. However. this doesn't affect
+  decompressing speed.
+
+- Very similar command line interface than what gzip and bzip2 have.

+#  v1.0: original release

+#  v1.2: keep source file, not bz2 one if eof while decompressing
+#  v1.3: reduce used cpu time (decompressing only one time;
+#        source crc error 're detected through PIPESTATUS)
+#  v1.4: add zip support on popular^h^h^h^h^hGwenole request
+#  v1.5:
+#        - make zip method acting as z one (remove original file,
+#          keeping only smallest file, displaying size gain, ...)
+#          thus giving occasion to factorize some common code
+#        - check that the source file does exists
+#        - handle corrupted zip source file
+#        - comment the script and verbos-ize() some old changes
+#        - use cheaper shell tests
+#        - add GPL reference
+#        - update online help to reflect optional options and newer
+#          supported formats
+#        - remove dependency on sed by using ${1%old}new_extension
+#  v1.6: 
+#        - print error message on stderr rather than on stdin
+#        - factorize/simplify zip method (fix erase temp files on bzip2ing
+#          error)
+#        - typo fixes
+#        - simplify for_each(file) loop
+#        - add "Know bugs" and TODO sections

+#        - if -k (keep) option is used, keep all files
+#  v1.7: handle file names with spaces
+#
+#  v1.7a: added support for lzmash (Giuseppe Ghibò, <ghibo@mandriva.com>)
+#
+#  v1.7b: updated to use new lzma command line tool which replaces old lzmash wrapper
+#	  (Per Øyvind Karlsen <pkarlsen@mandriva.com>)
+#
+#  v1.7c: use default compression level as -9 will take too much time and use too much
+#	  memory for decompression to make it worthwhile (Per Øyvind Karlsen <pkarlsen@mandriva.com>
