+	  PageKite is a protocol for dynamic, tunneled reverse proxying
+	  of arbitrary TCP byte streams. It is particularly well suited
+	  for making a HTTP server on a device without a public IP
+	  address visible to the wider Internet, but can also be used
+	  for a variety of other things, including SSH access.
+
+	  libpagekite is a tight, fast implementation of the PageKite
+	  protocol in C, suitable for high-performance or embedded
+	  applications.
+
+	  In addition to the libpagekite library, this package installs
+	  the pagekitec, sshkite and httpkite tools.
