+#
+#	Behaves just like "echo", but only triggers when idebug is on.

+# - "toplevel" is equivalent to 'frame', only it is automatically
+#   packed.
+# - The 'source', 'load', 'open', 'file' and 'exit' functions are
+#   mapped to corresponding functions in the parent interpreter.
+#
+# Further on, Tk cannot be really loaded. Still the safe 'load'
+# provedes a speciall case. The Tk can be divided into 4 groups,
+# that each has a safe handling procedure.
+#
+# - "::tkcon::SafeItem" handles commands like 'button', 'canvas' ......
+#   Each of these functions has the window name as first argument.
+# - "::tkcon::SafeManage" handles commands like 'pack', 'place', 'grid',
+#   'winfo', which can have multiple window names as arguments.
+# - "::tkcon::SafeWindow" handles all windows, such as '.'. For every
+#   window created, a new alias is formed which also is handled by
+#   this function.
+# - Other (e.g. bind, bindtag, image), which need their own function.
