<!-- ##### SECTION Long_Description ##### -->
<para>
#GtkCalendar is a widget that displays a calendar, one month at a time. 
It can be created with gtk_calendar_new().
</para>
<para>
The month and year currently displayed can be altered with 
gtk_calendar_select_month(). The exact day can be selected from the displayed 
month using gtk_calendar_select_day().
</para>
<para>
To place a visual marker on a particular day, use gtk_calendar_mark_day() 
and to remove the marker, gtk_calendar_unmark_day().
Alternative, all marks can be cleared with gtk_calendar_clear_marks().
</para>
<para>
The way in which the calendar itself is displayed can be altered using
gtk_calendar_set_display_options().
</para>
<para>
The selected date can be retrieved from a #GtkCalendar using
gtk_calendar_get_date().
</para>
<para>
If performing many 'mark' operations, the calendar can be frozen to prevent
flicker, using gtk_calendar_freeze(), and 'thawed' again using
gtk_calendar_thaw().
