+         The core of the XZ Utils compression code is based on LZMA SDK, but
+         it has been modified quite a lot to be suitable for XZ Utils.  The
+         primary compression algorithm is currently LZMA2, which is used
+         inside the .xz container format.  With typical files, XZ Utils
+         create 30 % smaller output than gzip and 15 % smaller output than
+         bzip2.
