+Balance is a simple but powerful generic tcp proxy with round robin load
+balancing and failover mechanisms. Its behaviour can be controlled at runtime
+using a simple command line syntax.
+
+The latest release now supports the definition of channel groups, connection
+counting, and handling. Boosting the power, and versatility of balance, one
+big step further.
