suppress all messages
-s, --dictionary-size=<bytes>
set dictionary size limit in bytes [8 MiB]
-t, --test
test compressed file integrity

be verbose (a 2nd -v gives more)

set compression level [default 6]
--fast
alias for -0
--best
alias for -9
If no file names are given, or if a file is '-', plzip compresses or
decompresses from standard input to standard output. Numbers may be
followed by a multiplier: k = kB = 10^3 = 1000, Ki = KiB = 2^10 =
1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc... Dictionary
sizes 12 to 29 are interpreted as powers of two, meaning 2^12 to 2^29
bytes.
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 --dictionary-size and --match-length
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 plzip to panic.
