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 option "--datadir" has been renamed to "--datarootdir" to

Pdlzip \- reduces the size of files
.SH SYNOPSIS

scale optimal for all files. If your files are large, very repetitive,
etc, you may need to use the \fB\-\-match\-length\fR and \fB\-\-dictionary\-size\fR
options directly to achieve optimal performance.

Return values: 0 for a normal exit, 1 for environmental problems (file
not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
invalid input file, 3 for an internal consistency error (eg, bug) which
caused pdlzip to panic.
