+%description
+The old version of Qt Assistant, based on Assistant Document Profile (.adp)
+files, and the associated QtAssistantClient library, for compatibility with
+applications providing help in that format.
+
+New applications should use the new version of Qt Assistant introduced in Qt
+4.4, based on the Qt Help Framework also introduced in Qt 4.4, instead.
