Have you looked at this code? Yes, there is: there is an "LZMA > compressed file format" and the 7z file format, both of which support > LZMA.

But there they are: http://ftp.gnu.org/gnu/coreutils/ [ ] coreutils-6.12.tar.gz 01-Jun-2008 05:03 8.6M [ ] coreutils-6.12.tar.lzma 01-Jun-2008 05:04 3.6M And there's a compressor in ports: archivers/lzma
