+#      This small application illustrates both the use of groups in combination
+#         of -composescale attributes and an implementation of kind of air traffic
+#         control electronic strips.
+#      However it is only a simplified example given as is, without any immediate usage!
+#
+#      3 strips formats are accessible through "+" / "-" buttons on the right side
+#
+#      1.   small-format: with 2 lines of info, and reduced length
+#
+#      2.   normal-format: with 3 lines of info, full length
+#
+#      3.  extended-format: with 3 lines of infos, full length
+#                           the 3 lines are zoomed
+#                           an additionnel 4th lone is displayed
+#
+#      An additionnal 4th format (micro-format) is available when double-clicking somewhere...
+#
+#      Strips can be moved around by drag&drop from the callsign
+#
+#      When changing size, strips are animated. The animation is a very simple one,
+#        which should be enhanced.... You can change the animation parameters, by modifyng
+#        $delay and $steps.
