+	help
+	  Build a cloop root filesystem
+
+	  cloop is a Linux kernel module that enables compressed
+	  loopback filesystem support. With it you can mount a
+	  compressed filesystem like a block device and seamlessly
+	  decompress its data while accessing it.  The majority of the
+	  software on an LNX-BBC is accessed in this fashion.
