+=== HTTP Support
+
+The library may be configured with support for HTTP, and this will
+be the case if WebSocket support is configured as well.  In this case,
+it is possible to access functionality to support the creation of
+HTTP (and HTTP/S if TLS support is present) servers and clients.
+
+==== Common HTTP Functions
+
+The following functions are used to work with HTTP requests, responses,
+and connections.
