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
"public domain" version of the lzip data compressor, intended for those
who can't distribute GPL licensed Free Software.
The lzip file format is designed for long-term data archiving. It is
clean, provides very safe 4 factor integrity checking, and is backed by
the recovery capabilities of lziprecover.
Pdlzip is also able to decompress legacy lzma-alone (.lzma) files.
Pdlzip is written in C.
Pdlzip includes public domain compression code from the LZMA SDK written
by Igor Pavlov.
Learn more about lzip in the Lzip Home Page.
Pdlzip only includes a man page and a README file. For information about
the lzip file format see the online manual of lzip below.
The manual is available in the info system of the GNU
Operating System. Use info to access the top level info
page. Use info lzip to access the lzip section directly.
