+# This is not an automatic gtk+-1.x to gtk+-2.x port tool,
+# just a tool that ease perl apps' gtk2 port.
+# you'll have to fix all remaining problems, beginning by spotted warnings
+# it'll save you basic conversion work
+#
+# if you used Gtk::Text, a little more work will be needed (look at logdrake gtk2 port)
+# if you used Gtk::CTree, Gtk::CList or worse, Gtk::Tree, you'll need quite a lot of exhausting work :-(
