 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.

 The bidimensional parameter space of LZMA can't be mapped to a linear
 scale optimal for all files. If your files are large, very repetitive,
-etc, you may need to use the \fB\-\-dictionary\-size\fR and \fB\-\-match\-length\fR
-options directly to achieve optimal performance. For example, \fB\-9m64\fR
-usually compresses executables more (and faster) than \fB\-9\fR.

 Exit status: 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.
