-#

-    ##
-    ## If you set ::tkcon::OPT(exec) to {}, then instead of a multiple

-    ## This can be useful when attaching to programs that like to operate
-    ## in the main interpter (for example, based on special wish'es).
-    ## You can set this from the command line with -exec ""
-    ## A side effect is that all tkcon command line args will be used
-    ## by the first console only.

-## idebug - interactive debugger
-#
-# idebug body ?level?
-#
-#	Prints out the body of the command (if it is a procedure) at the
-#	specified level.  <i>level</i> defaults to the current level.
-#
-# idebug break
-#
-#	Creates a breakpoint within a procedure.  This will only trigger
-#	if idebug is on and the id matches the pattern.  If so, TkCon will
-#	pop to the front with the prompt changed to an idebug prompt.  You
-#	are given the basic ability to observe the call stack an query/set
-#	variables or execute Tcl commands at any level.  A separate history
-#	is maintained in debugging mode.
-#
-# idebug echo|{echo ?id?} ?args?
-#
-#	Behaves just like "echo", but only triggers when idebug is on.
-#	You can specify an optional id to further restrict triggering.
-#	If no id is specified, it defaults to the name of the command
-#	in which the call was made.
-#
-# 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 *.
-#
-# idebug off
-#
-#	Turns idebug off.
-#
-# idebug on ?id?
-#
-#	Turns idebug on.  If 'id' is specified, it sets the id to it.
-#
-# idebug puts|{puts ?id?} args
-#
-#	Behaves just like "puts", but only triggers when idebug is on.
-#	You can specify an optional id to further restrict triggering.
-#	If no id is specified, it defaults to the name of the command
-#	in which the call was made.
-#
-# idebug show type ?level? ?VERBOSE?
-#
-#	'type' must be one of vars, locals or globals.  This method
-#	will output the variables/locals/globals present in a particular
-#	level.  If VERBOSE is added, then it actually 'dump's out the
-#	values as well.  'level' defaults to the level in which this
-#	method was called.
-#
-# idebug trace ?level?
-#
-#	Prints out the stack trace from the specified level up to the top
-#	level.  'level' defaults to the current level.

-# Here is a group of functions that is only used when Tkcon is

-#
-# - "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.
