15 xz-utils replaced lzma-utils. According to lzma-utils website
16 (http://tukaani.org/lzma/):
17
18 "LZMA Utils are legacy data compression software with high compression
19 ratio. LZMA Utils are no longer developed, although critical bugs may
20 be fixed as long as fixing them doesn't require huge changes to the
21 code.
22
23 Users of LZMA Utils should move to XZ Utils. XZ Utils support the
24 legacy .lzma format used by LZMA Utils, and can also emulate the
25 command line tools of LZMA Utils. This should make transition from
26 LZMA Utils to XZ Utils relatively easy. "
