The liblzma library for LZMA2 lossless data compression algorithm and
the userland utilities xz(1), xzdec(1), lzma(1), and lzmainfo(1). has
been imported. When the old system is upgraded to 8.1-RELEASE,
deinstalling a version found in the Ports Collection (archivers/xz) and
recompilation of the packages which depend on it may be required.
