- gzip -cd pdlzip[version].tar.gz | tar -xf -

-The options "-f, --force", "-F, --recompress", "-k, --keep", and
-"-o, --output", have been ported from clzip.
+Decompressing and testing no more show file version in lzip mode.
-Pdlzip now accepts more than one file in the command line.
-
-Decompression time has been reduced by 5%.
-
-The dependence of "-t" on the existence of "/dev/null" has been removed.
-
-The value returned by "-d" and "-t" in case of data error has been fixed.
-
-Information shown at verbosity levels 2 and 3 has been changed.
-
-Option "-n, --threads" is now accepted and ignored for compatibility
-with plzip.
-
-"configure" now accepts options with a separate argument.
-
-Configure option "--datadir" has been renamed to "--datarootdir" to
-follow GNU Standards.
-
-The target "install-as-lzip" has been added to the Makefile.

-The target "install-bin" has been added to the Makefile.

Description
-Pdlzip is a lossless data compressor based on the LZMA algorithm, with
-very safe integrity checking and a user interface similar to the one of
-gzip or bzip2. Pdlzip decompresses almost as fast as gzip and compresses
-better than bzip2, which makes it well suited for software distribution
-and data archiving.
+Pdlzip is a lossless data compressor with a user interface similar to
+the one of lzip, bzip2 or gzip.
Pdlzip uses the lzip file format; the files produced by pdlzip are
(hope)fully compatible with lzip-1.4 or newer. Pdlzip is in fact a
