+Pen is a load balancer for "simple" tcp based protocols such as http or
+smtp.  It allows several servers to appear as one to the outside and
+automatically detects servers that are down and distributes clients among
+the available servers.  This gives high availability and scalable
+performance.
+
+  The load balancing algorithm keeps track of clients and will try to
+send them back to the server they visited the last time.  The client
+table has a number of slots (default 2048, settable through command-line
+arguments).  When the table is full, the least recently used one will
+be thrown out to make room for the new one.
+
+  This is superior to a simple round-robin algorithm, which sends a client
+that connects repeatedly to different servers.  Doing so breaks
+applications that maintain state between connections in the server,
+including most modern web applications.
+
+  When pen detects that a server is unavailable, it scans for another
+starting with the server after the most recently used one.  That way
+we get load balancing and "fair" failover for free.
