+Summary:Meals for university canteens
+Description:
+OpenMensa shows you what you can eat in the cafeteria or canteen at your
+university. At the moment about 150 canteens in German speaking countries are
+supported. In order to get today's meal plan, this app connects to the
+database at http://openmensa.org/.
+
+Anti-feature:NonFreeNet. It seems that the on-line database server is to be
+open-sourced sometime in the near future, although currently it is still not.
