+/********************** Server (Reciever) Interfaces *************************/
+
+/* On the server side, the caller will recieve data from the incoming
+ socket and pass it to icalcstps_next_input. The caller then takes
+ the return from icalcstps_next_outpu and sends it out through the
+ socket. This gives the caller a point of control. If the cstp code
+ connected to the socket itself, it would be hard for the caller to
+ do anything else after the cstp code was started.
+
+ All of the server and client command routines will generate
+ response codes. On the server side, these responses will be turned
+ into text and sent to the client. On the client side, the reponse
+ is the one sent from the server.
+
+ Since each command can return multiple responses, the responses are
+ stored in the icalcstps object and are accesses by
+ icalcstps_first_response() and icalcstps_next_response()
+
+ How to use:
+
+ 1) Construct a new icalcstps, bound to your code via stubs
+ 2) Repeat forever:
+ 2a) Get string from client & give to icalcstps_next_input()
+ 2b) Repeat until icalcstp_next_output returns 0:
+ 2b1) Call icalcstps_next_output.
+ 2b2) Send string to client.
