Lunzip is a decompressor for the lzip format. It is written in C and its
small size makes it well suited for embedded devices or software
installers that need to decompress files but don't need compression
capabilities. Lunzip is fully compatible with lzip-1.4 or newer.

Lunzip provides a 'low memory' mode able to decompress any file using as
little memory as 50 kB, irrespective of the dictionary size used to
compress the file. To activate it, specify the size of the output buffer
with the '--buffer-size' option and lunzip will use the decompressed
file as dictionary for distances beyond the buffer size. Of course, the
smaller the buffer size used in relation to the dictionary size, the
more accesses to disk are needed and the slower the decompression is.
This 'low memory' mode only works when decompressing to a regular file
and is intended for systems without enough memory (RAM + swap) to keep
the whole dictionary at once.

Usage: D:\films\lzip-1.20.tar\lunzip.exe [options] [files]

Options:
  -h, --help                 display this help and exit
  -V, --version              output version information and exit
  -a, --trailing-error       exit with error status if trailing data
  -c, --stdout               write to standard output, keep input files
  -d, --decompress           decompress (this is the default)
  -f, --force                overwrite existing output files
  -k, --keep                 keep (don't delete) input files
  -l, --list                 print (un)compressed file sizes
  -o, --output=<file>        if reading standard input, write to <file>
  -q, --quiet                suppress all messages
  -t, --test                 test compressed file integrity
  -u, --buffer-size=<bytes>  set output buffer size in bytes
  -v, --verbose              be verbose (a 2nd -v gives more)
If no file names are given, or if a file is '-', lunzip 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...
Buffer sizes 12 to 29 are interpreted as powers of two, meaning 2^12
to 2^29 bytes.

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 lunzip to panic.
