+	---help---
+	  CCID-3 denotes TCP-Friendly Rate Control (TFRC), an equation-based
+	  rate-controlled congestion control mechanism.  TFRC is designed to
+	  be reasonably fair when competing for bandwidth with TCP-like flows,
+	  where a flow is "reasonably fair" if its sending rate is generally
+	  within a factor of two of the sending rate of a TCP flow under the
+	  same conditions.  However, TFRC has a much lower variation of
+	  throughput over time compared with TCP, which makes CCID-3 more
+	  suitable than CCID-2 for applications such streaming media where a
+	  relatively smooth sending rate is of importance.
+
+	  CCID-3 is further described in RFC 4342,
+	  http://www.ietf.org/rfc/rfc4342.txt
+
+	  The TFRC congestion control algorithms were initially described in
+	  RFC 5348.
+
+	  This text was extracted from RFC 4340 (sec. 10.2),
