Matias, sure, this can be done.

But bbox already has *two* LZMA decompressors.
Feels wrong, isn't it?

In the long run it would be a nightmare to have two
or more LZMA (de)compressors in common use on Linux.

What happened between lzip and xz? Are they incompatible?
On what level? File format, or compression stream format too?
