Cal-util:

- calobj.h depends on libversit/vcc.h, because it uses a VObject for
  ical_object_create_from_vobject().  This should be an internal
  function in the PCS and nothing else (we do not install libversit,
  so our public libraries should not depend on it).

- Or maybe we *should* install libversit, since the addressbook code
  uses it as well.

- timeutil has a lot of crap and some namespace pollution.  Clean it
  up.

PCS:

- When loading a calendar, substitute duplicated UIDs by new ones, and
  possibly print out a warning message.

----- Old Gnomecal TODO starts here -----

Pilot:

* Better support for untimed events (we have none now).

* Hash objects based on their UIDs.

* Add placeholders for deleted events, so that we can kill those
  when syncing to the pilot.

BUGS:

- Recurrence end date is wrong.  An event that repeats daily will not
  be included in the ending date of the recurrence (off-by-one
  error?).

- X-fields (extensions) are stripped from a vCal file when it is
  saved.  They should be preserved.

Features:

- Add a calendar-week so that people know which week of the year it is

Year view:

- See why it is so fucking slow when opening its notebook page for the
  first time.

Month view:

- Popup menu like in the year view.

- Double click on a day takes you to the day view.

- DnD of appointments to move them around.

Week view:

- Nice display as in the Palm Pilot.

Day view:

- Rewrite in terms of the canvas and make it pretty.

Preferences:

- BUG: 12/24 hours stuff is not consistent - I remember that on editing
  new appointment you get the time-selectors always on 12-hr format

Event editor dialog:

- Make it figure out whether the alarm is in
  minutes/hours/days/etc. (via a cascade of conditions) and set the
  widgets appropriately.

Gnome date selection widget:

- Make the displayed date be localized properly -- use strftime().

General:

- Write online help.  Nice help.  Lots of help.

- If you leave the calendar running overnight, the "current day"
  marker in the GnomeMonthItems does not get updated.

- Add categories support.  Color-coded categories.

- Untimed events
