This is a readme for lzma in busybox, buildroot, kernel and standalone.

This is in use by floppyfw, both the floppyfw itself and the corresponding 
floppyfw devkit based on buildroot.

The feature common for all these packages are that they use the zlib/stream 
based method as used by the lzma patched mksquashfs found at 
http://oleg.wl500g.info/

Thanks to Ming-Ching Tiew <mctiew@yahoo.com> for lzmatools and the kernel
patch.

lzmatools

a compressor and decompressor. both pretty simple.

This requires the lzma sdk version 4.06 to compile.

Kernel LZMA compression:

This is a patch to use lzma for compressing/decompressing vmlinux and
it is alot better than bzImage and UPX. It does need lzmacomp from the 
lzmatools package.

The one here is for 2.4 and for 2.6 you have:

http://www.geocities.com/mctiew/ffw/lzma-vmlinuz-2.6.patch.gz

which uses "lzma", the lzmacomp equivalent in the 7zip lzma SDK.

Busybox:

lzmacat is a busybox adaption of the lzmacat in the izmatools package.

Buildroot stuff:

lzmatools-buildroot.tgz is make files for lzmatools

lzma-buildroot.tgz is a separate lzma tool from 
http://martinus.geekisp.com/rublog.cgi/Projects/LZMA
This is not compatible with the other lzma based tools and patches
here and seems to be a dead end..
