+#   ATTENTION: Expect is brain-dead: it requires private Tcl information
+#   (tclInt.h) which only can be found in the Tcl sources on the one
+#   hand and it requires the Tcl installation files under run-time on
+#   the other hand (which can be provided by the Tcl package). This
+#   means we have to do something very strange: include the Tcl source
+#   and use it for building and requiring the Tcl package for use under
+#   run-time. Hence we require _exactly_ a particular Tcl version. Keep
+#   this in sync!
