+        /**@file icaltime.h
+         *@brief struct icaltimetype is a pseudo-object that abstracts time
+         *handling.
+ *
+         *It can represent either a DATE or a DATE-TIME (floating, UTC or in a
+         *given timezone), and it keeps track internally of its native timezone.
+ *
+         *The typical usage is to call the correct constructor specifying the
+         *desired timezone. If this is not known until a later time, the
+         *correct behavior is to specify a NULL timezone and call
+         *icaltime_convert_to_zone() at a later time.
+ *
+         *There are several ways to create a new icaltimetype:
+ *
+         *- icaltime_null_time()
+         *- icaltime_null_date()
+         *- icaltime_current_time_with_zone()
+         *- icaltime_today()
+         *- icaltime_from_timet_with_zone(time_t tm, int is_date,
+         *      icaltimezone *zone)
+         * - icaltime_from_string_with_zone(const char* str, icaltimezone *zone)
+         *- icaltime_from_day_of_year(int doy,  int year)
+         *- icaltime_from_week_number(int week_number, int year)
+ *
+         *italtimetype objects can be converted to different formats:
+ *
+         *- icaltime_as_timet(struct icaltimetype tt)
+         *- icaltime_as_timet_with_zone(struct icaltimetype tt,
+         *      icaltimezone *zone)
+         *- icaltime_as_ical_string(struct icaltimetype tt)
+ *
+         *Accessor methods include:
+ *
+         *- icaltime_get_timezone(struct icaltimetype t)
+         *- icaltime_get_tzid(struct icaltimetype t)
+         *- icaltime_set_timezone(struct icaltimetype t, const icaltimezone *zone)

-/********************** 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.
