Please, test it and report any bugs you find.

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.

The lzip file format is designed for data sharing and long-term 
archiving, taking into account both data integrity and decoder availability.

Pdlzip is also able to decompress legacy lzma-alone (.lzma) files. 
Lzma-alone is a very bad format; it is essentially a raw LZMA stream. If 
you keep any lzma-alone files, it is advisable to recompress them to 
lzip format. Lziprecover can convert some lzma-alone files to lzip 
format without recompressing.

Pdlzip includes public domain (de)compression code from the LZMA SDK 
(Software Development Kit) written by Igor Pavlov. Pdlzip is in fact a 
permissively licensed implementation of the lzip data compressor, 
intended for those who can't distribute (or even use) GPL licensed Free 
Software.

Changes in this version:

  * The option '--loose-trailing', has been added.

  * The test used by pdlzip to discriminate trailing data from a 
corrupt header in multimember or concatenated files has been improved to 
a Hamming distance (HD) of 3, and the 3 bit flips must happen in 
different magic bytes for the test to fail. As a consequence some kinds 
of files no longer can be appended to a lzip file as trailing data 
unless the '--loose-trailing' option is used when decompressing.
Lziprecover can be used to remove conflicting trailing data from a file.

  * The 'bits/byte' ratio has been replaced with the inverse 
compression ratio in the output.

  * A final diagnostic is now shown at verbosity level 1 (-v) or higher 
if any file fails the test when testing multiple files.

  * A second '.lz' extension is no longer added to the argument of '-o' 
if it already ends in '.lz' or '.tlz'.

  * In case of (de)compressed size mismatch, the stored size is now 
also shown in hexadecimal to ease visual comparison.

  * The dictionary size is now shown at verbosity level 4 (-vvvv) when 
decompressing or testing.
