- ## A side effect is that all tkcon command line args will be used

-# idebug id ?id?
-#
-# Query or set the idebug id. This id is used by other idebug
-# methods to determine if they should trigger or not. The idebug
-# id can be a glob pattern and defaults to *.

-# Here is a group of functions that is only used when Tkcon is
-# executed in a safe interpreter. It provides safe versions of
-# missing functions. For example:
-#
-# - "tk appname" returns "tkcon.tcl" but cannot be set
-# - "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.
