Update spanish translation for the Calendar.

Update spanish translation for the Calendar.

Added command line handling to the calendar program.  You can now
display your appointments for any given date from the command line
wihtout running X.

Added CVS's `getdate'.  This is a date parser for a bunch of formats.

Internationalized getdate.  You can even type date descriptions in
your native language.

Miguel.

+<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".
