+     "ConfClerk is an application written in Qt, which makes conference schedules
+available offline.  It displays the conference schedule from various views,
+support searches on various items (speaker, speech topic, location, etc.) and
+enables you to select favorite events and create your own schedule.
+
+At the moment ConfClerk is able to import schedules in XML format created by
+the PentaBarf conference management system (or frab) used by e.g. FOSDEM,
+DebConf, FrOSCon, Grazer LinuxTage, and the CCC congresses.
+
+ConfClerk is targeted at mobile devices but works on any system running Qt.")
