Subject: [PATCH] Document the liblzma support. Unfortunately, liblzma itself
 is GPLed, so unlikely to become part of the FreeBSD base system. However, the
 core lzma compression/decompression code is public domain, so it should be
 feasible for someone to create a compatible library without the GPL strings.
