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)

       lzma, unlzma, lzcat - LZMA compression and decompression tool

       lzma [-123456789cdefhkLqtvV] [-S suffix] [filenames ...]
       unlzma [-cfhkLqtvV] [-S suffix] [filenames ...]
       lzcat [-fhLqV] [filenames ...]

$ lzma --help

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.
