There is a problem with the man page of this package. From the README,
it is lifted from the debian package. However, the debian package must
be a totally different version of lzma, because it does not correspond
at all to the one shipped here:
LZMA(1) LZMA(1)
NAME
lzma, unlzma, lzcat - LZMA compression and decompression tool
SYNOPSIS
lzma [-123456789cdefhkLqtvV] [-S suffix] [filenames ...]
unlzma [-cfhkLqtvV] [-S suffix] [filenames ...]
lzcat [-fhLqV] [filenames ...]
$ lzma --help
LZMA 4.43 Copyright (c) 1999-2006 Igor Pavlov 2006-06-04
Error: Incorrect command
Usage: LZMA <e|d> inputFile outputFile [<switches>...]
e: encode file
d: decode file
b: Benchmark
<Switches>
-a{N}: set compression mode - [0, 1], default: 1 (max)
-d{N}: set dictionary - [0,30], default: 23 (8MB)
-fb{N}: set number of fast bytes - [5, 273], default: 128
-mc{N}: set number of cycles for match finder
-lc{N}: set number of literal context bits - [0, 8], default: 3
-lp{N}: set number of literal pos bits - [0, 4], default: 0
-pb{N}: set number of pos bits - [0, 4], default: 2
-mf{MF_ID}: set Match Finder: [bt2, bt3, bt4, hc4], default: bt4
-eos: write End Of Stream marker
-si: read data from stdin
-so: write data to stdout
The man page talks about a version that has the same interface as gzip
and bzip2, however the binary that is in the package has a totally
different set of options -- it would actually be nice to have the debian
version instead of this.
Also, the manpage refers to unlzma and lzcat which are nonexistant.
