Rainlendar is a very customizable calendar that resides on your desktop and
shows the days of the current month. The calendar can use different skins
to fit your taste (and theme). You can use different fonts and colors,
select the background image or even make the calendar's background
transparent. All the customization can be done with a simple GUI.
The calendar can also synchronize the events with a server, which will
allow you to use it e.g. at home and at work. There are plenty of other
features too. Check the rest of this document for details.
