+ (description
+ "Endlessh is an SSH tarpit that very slowly sends an endless, random SSH
+banner. It keeps SSH clients locked up for hours or even days at a time. The
+purpose is to put your real SSH server on another port and then let the script
+kiddies get stuck in this tarpit instead of bothering a real server.
+
+Since the tarpit is in the banner before any cryptographic exchange occurs, this
+program doesn't depend on any cryptographic libraries. It's a simple,
+single-threaded, standalone C program. It uses @code{poll()} to trap multiple
+clients at a time.")
