+##
+## DESCRIPTION
+##	Implements a console mega-widget

+## ARGUMENTS
+##	console <window pathname> <options>
+##
+## OPTIONS
+##	(Any toplevel widget option may be used in addition to these)
+##
+##  -blinkcolor color			DEFAULT: yellow
+##	Specifies the background blink color for brace highlighting.
+##	This doubles as the highlight color for the find box.
+##
+##  -blinkrange TCL_BOOLEAN		DEFAULT: 1
+##	When doing electric brace matching, specifies whether to blink
+##	the entire range or just the matching braces.
+##
+##  -proccolor color			DEFAULT: darkgreen
+##	Specifies the color to highlight recognized procs.
+##
+##  -promptcolor color			DEFAULT: brown
+##	Specifies the prompt color.
+##
+##  -stdincolor color			DEFAULT: black
+##	Specifies the color for "stdin".
+##	This doubles as the console foreground color.
+##
+##  -stdoutcolor color			DEFAULT: blue
+##	Specifies the color for "stdout".
+##
+##  -stderrcolor color			DEFAULT: red
+##	Specifies the color for "stderr".
+##
+##  -blinktime delay			DEFAULT: 500
+##	For electric brace matching, specifies the amount of time to
+##	blink the background for.
+##
+##  -cols ##				DEFAULT: 80
+##	Specifies the startup width of the console.
+##
+##  -grabputs TCL_BOOLEAN		DEFAULT: 1
+##	Whether this console should grab the "puts" default output
+##
+##  -lightbrace TCL_BOOLEAN		DEFAULT: 1
+##	Specifies whether to activate electric brace matching.
+##
+##  -lightcmd TCL_BOOLEAN		DEFAULT: 1
+##	Specifies whether to highlight recognized commands.
+##
+##  -rows ##				DEFAULT: 20
+##	Specifies the startup height of the console.
+##
+##  -scrollypos left|right		DEFAULT: right
+##	Specified position of the console scrollbar relative to the text.
+##
+##  -showmultiple TCL_BOOLEAN		DEFAULT: 1
+##	For file/proc/var completion, specifies whether to display
+##	completions when multiple choices are possible.
+##
+##  -showmenu TCL_BOOLEAN		DEFAULT: 1
+##	Specifies whether to show the menubar.
+##
+##  -subhistory TCL_BOOLEAN		DEFAULT: 1
+##	Specifies whether to allow substitution in the history.
+##
+## RETURNS: the window pathname
+##
+## BINDINGS (these are the bindings for Console, used in the text widget)
+##
+## <<Console_ExpandFile>>	<Key-Tab>
+## <<Console_ExpandProc>>	<Control-Shift-Key-P>

+##
+## METHODS
+##	These are the methods that the console megawidget recognizes.
+##
+## configure ?option? ?value option value ...?
+## cget option
+##	Standard tk widget routines.
+##
+## load ?filename?
+##	Loads the named file into the current interpreter.
+##	If no file is specified, it pops up the file requester.
+##
+## save ?filename?
+##	Saves the console buffer to the named file.
+##	If no file is specified, it pops up the file requester.
+##
+## clear ?percentage?
+##	Clears a percentage of the console buffer (1-100).  If no
+##	percentage is specified, the entire buffer is cleared.
+##
+## error
+##	Displays the last error in the interpreter in a dialog box.
+##
+## hide
+##	Withdraws the console from the screen
+##
+## history ?-newline?
+##	Prints out the history without numbers (basically providing a
+##	list of the commands you've used).
+##
+## show
+##	Deiconifies and raises the console
+##
+## subwidget widget
+##	Returns the true widget path of the specified widget.  Valid
+##	widgets are console, scrolly, menubar.
+##
+## NAMESPACE & STATE
+##	The megawidget creates a global array with the classname, and a
+## global array which is the name of each megawidget created.  The latter
+## array is deleted when the megawidget is destroyed.
+##	The procedure console and those beginning with Console are
+## used.  Also, when a widget is created, commands named .$widgetname
+## and Console$widgetname are created.
+##
+## EXAMPLE USAGE:
+##
+## console .con -rows 24 -showmenu false
