`DS (coded dictionary size, 1 byte)'
Bits 4-0 contain the base 2 logarithm of the base dictionary size.
Bits 7-5 contain the number of "wedges" to substract from the base
dictionary size to obtain the dictionary size. The size of a wedge
is (base dictionary size / 16).
Lzip divides the distance between any two powers of 2 into 8
equally spaced intervals, named "wedges". The dictionary size is
calculated by taking a power of 2 (the base size) and substracting
from it a number of wedges between 0 and 7. The size of a wedge is
(base_size / 16).
Bits 4-0 contain the base 2 logarithm of the base size (12 to 29).
Bits 7-5 contain the number of wedges (0 to 7) to substract from
the base size to obtain the dictionary size.
Example: 0xD3 = (2^19 - 6 * 2^15) = (512KiB - 6 * 32KiB) = 320KiB
Valid values for dictionary size range from 4KiB to 512MiB.

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.

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 minilzip to panic.
