+qdebug-odebug.py (C) 2004 Michael 'Mickey' Lauer <mickey@Vanille.de>
+This script helps to convert from the Qt debugging framework to the Opie debugging framework
+Though it will take care of the most common usages, it may not recognize uncommon ones, hence
+manual work may be needed after applying the script.
