1998-04-18 Miguel de Icaza <miguel@nuclecu.unam.mx>
+ * gnome-cal.html: Added small documentation.
+
+ * main.c: Add more icons to the menus; Rename some menubar
+ entries; Add `new' icon to the toolbar.
+ (dump_events): Added argument handling and dumping of events from
+ the command line. Extremely cool.
+
+ * getdate.y: Taken from the CVS source code. Used for date
+ parsing in the command line.
+
+ Internationalized getdate.y. Wee! It even works with spanish.
+
* calobj.c (ical_object_to_vobject): Add Quoted printable property
to items containing new lines.
(duration): Use unsigned integers, to work around buggy calendar

+<p>
+The GNOME calendar program is the calendaring program of the GNOME
+system. It uses the vCalendar standard for transfering calendar
+information (and is also the on-disk format used).
+
+<p>
+
+<a name="cmdline">
+<h2>Command line options</h2>
+
+Several options are available on the command line, they are:
+<ul>
+ <li><tt>--events</tt> Displays the events for the date
+ specified (or today, if no date is specified).
+
+ <li><tt>--from DATE</tt> Define the beginning of the range for
+ the event display, or the startup day on the calenday views.
+ By default, the event will span the whole day specified in
+ DATE.
+
+ <li><tt>--to DATE</tt> Define the range end for the event
+ display. If this is not specified, it will default to the end
+ of the day specified by the <tt>--from</tt> option.
+
+ <li><tt>--file FILE</tt> Set the calendar to the FILE
+ specified on the command line.
+</ul>
+
+<p>
+
+DATE is interpreted as being in the local time- zone, unless a
+specific timezone is specified. Examples of valid date specifications
+include: "1 month ago", "2 hours ago", "400000 seconds ago", "last
+year", "last Monday", "yesterday", "a fortnight ago", "3/31/92
+10:00:07 PST", "January 23, 1987 10:05pm", "22:00 GMT".

+The GNOME calendar program is the calendaring program of the GNOME
+system. It uses the vCalendar standard for transfering calendar
+information (and is also the on-disk format used).
+
+<p>
+
+<a name="cmdline">
+<h2>Command line options</h2>
+
+Several options are available on the command line, they are:
+<ul>
+ <li><tt>--events</tt> Displays the events for the date
+ specified (or today, if no date is specified).
+
+ <li><tt>--from DATE</tt> Define the beginning of the range for
+ the event display, or the startup day on the calenday views.
+ By default, the event will span the whole day specified in
+ DATE.
+
+ <li><tt>--to DATE</tt> Define the range end for the event
+ display. If this is not specified, it will default to the end
+ of the day specified by the <tt>--from</tt> option.
+
+ <li><tt>--file FILE</tt> Set the calendar to the FILE
+ specified on the command line.
+</ul>
+
+<p>
+
+DATE is interpreted as being in the local time- zone, unless a
+specific timezone is specified. Examples of valid date specifications
+include: "1 month ago", "2 hours ago", "400000 seconds ago", "last
+year", "last Monday", "yesterday", "a fortnight ago", "3/31/92
+10:00:07 PST", "January 23, 1987 10:05pm", "22:00 GMT".
