+ <description>
+  <p>
+   Screenruler is a program used to measure distances on your screen. You can
+   change the ruler to apply to your zoomlevel. Different measurment units e.g.
+   Centimeters can be chosen. It is easy to use and does what you would expect 
+   from a virtual ruler without any additional gimmicks.
