+/// This is the KTouch lecture editor dialog.
+///
+/// The lecture edit dialog works like a standalone edit tool for editing lectures.
+/// Upon opening of the dialog the 'open lecture' dialog box is shown where
+/// the user can either select a local training lecture or load a lecture file.
+/// Then the user can edit the lecture and save it (if desired under a different
+/// file name).
+/// The use of the editor is simple, just include ktouchlectureeditor.h and do
+/// @code
+///  KTouchLectureEditor dlg;
+///  bool ok = dlg.startEditor(current_lecture);
+///  // current_lecture should be the URL pointing to the current/default 
+///  // lecture or an empty URL
+/// @endcode
+/// @see startEditor() for details on the return value.
