This only works if you have those programs installed from the archivers/lzmautils-devel port, of course, and it's significantly slower than using the library support. There is an option in libarchive to compile against the liblzma library for direct support of these formats. Of course, that requires you to have the libraries installed first (from archivers/lzmautils-devel port) and then recompiling libarchive. (See comments in /usr/src/lib/libarchive/Makefile for how to turn on the liblzma support.) I would like to import liblzma (not liblzmadec) into the FreeBSD base system. Liblzma is generously licensed and supports both writing and reading and also supports the newer "xz" file format. Once that is done, we can turn on the full libarchive/bsdtar support for lzma/xz by default. I don't have time to work on this right now, unfortunately. Tim
