lzma details ,pls help!!!

Hi all,

I am working on a OS which is in the livecd fomat(its also installable)..
the issues is that its LZMA -7 compressed!!!
After a few unsuccessful attempts ,Is when i figured out that it was lzma compressed.....
Also am working on manipulating the ramdisk ..
But when i tried a putback (i obviously need to decompress first then compress it back)
I uncompressed the ramdisk ,
using gzcat then tried compressing back with gzip -c Smilie

(Its wrong i know!!)

After a few unsuccessful attempts ,Is when i figured out that it was lzma compressed.....

Anyway now i would like to know details of how i can compress and using LZMA?
I am working on solairs (b83)
So please specify the packages i need to install in order to run LZMA!!!

Thanks

xzless

XZLESS(1)							     XZ Utils								 XZLESS(1)

NAME

       xzless, lzless - view xz or lzma compressed (text) files

SYNOPSIS

       xzless [file...]
       lzless [file...]

DESCRIPTION

       xzless  is  a  filter  that  displays text from compressed files to a terminal.	It works on files compressed with xz(1) or lzma(1).  If no
       files are given, xzless reads from standard input.

       xzless uses less(1) to present its output.  Unlike xzmore, its choice of pager cannot be altered by setting an environment variable.   Com-
       mands are based on both more(1) and vi(1) and allow back and forth movement and searching.  See the less(1) manual for more information.

       The command named lzless is provided for backward compatibility with LZMA Utils.

ENVIRONMENT

       LESSMETACHARS
	      A list of characters special to the shell.  Set by xzless unless it is already set in the environment.

       LESSOPEN
	      Set to a command line to invoke the xz(1) decompressor for preprocessing the input files to less(1).

SEE ALSO

       less(1), xz(1), xzmore(1), zless(1)
