+	help
+	  XZ is the successor to the Lempel-Ziv/Markov-chain Algorithm
+	  compression format, which provides memory-hungry but powerful
+	  compression (often better than bzip2) and fast, easy decompression.
+
+	  This package provides the command line tools for working with XZ
+	  compression, including xz, unxz, xzcat, xzgrep, and so on. They can
+	  also handle the older LZMA format, and if invoked via appropriate
+	  symlinks will emulate the behavior of the commands in the lzma
+	  package.
