+        /**@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)
+         *- icaltime_day_of_year(struct icaltimetype t)
+         *- icaltime_day_of_week(struct icaltimetype t)

  Icalset is the "base class" for representations of a collection of
  iCal components. Derived classes (actually delegatees) include:
  
-    icalfileset   Store componetns in a single file
+    icalfileset   Store components in a single file
     icaldirset    Store components in multiple files in a directory
+    icalbdbset    Store components in a Berkeley DB File
     icalheapset   Store components on the heap
     icalmysqlset  Store components in a mysql database.

-   socket and pass it to icalcstps_next_input. The caller then takes
-   the return from icalcstps_next_outpu and sends it out through the

-
-   All of the server and client command routines will generate

-   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
