+This directory contains a collection of programs to demonstrate
+the features of the Tk toolkit.  The programs are all scripts for
+"wish", a windowing shell.  If wish has been installed in /usr/local
+then you can invoke any of the programs in this directory just
+by typing its file name to your command shell.  Otherwise invoke
+wish with the file as its first argument, e.g., "wish hello".
+The rest of this file contains a brief description of each program.
+Files with names ending in ".tcl" are procedure packages used by one
+or more of the demo programs;  they can't be used as programs by
+themselves so they aren't described below.
+
+hello -		Creates a single button;  if you click on it, a message
+		is typed and the application terminates.
+
+widget -	Contains a collection of demonstrations of the widgets
+		currently available in the Tk library.  Most of the .tcl
+		files are scripts for individual demos available through
+		the "widget" program.
+
+ixset -		A simple Tk-based wrapper for the "xset" program, which
+		allows you to interactively query and set various X options
+		such as mouse acceleration and bell volume.  Thanks to
+		Pierre David for contributing this example.

+{This window is a text widget.  It displays one or more lines of text
+and allows you to edit the text.  Here is a summary of the things you
+can do to a text widget:
+
+1. Scrolling. Use the scrollbar to adjust the view in the text window.
+
+2. Scanning. Press mouse button 2 in the text window and drag up or down.
+This will drag the text at high speed to allow you to scan its contents.
+
+3. Insert text. Press mouse button 1 to set the insertion cursor, then
+type text.  What you type will be added to the widget.
+
+4. Select. Press mouse button 1 and drag to select a range of characters.
+Once you've released the button, you can adjust the selection by pressing
+button 1 with the shift key down.  This will reset the end of the
+selection nearest the mouse cursor and you can drag that end of the
+selection by dragging the mouse before releasing the mouse button.
+You can double-click to select whole words or triple-click to select
+whole lines.
+
+5. Delete and replace. To delete text, select the characters you'd like
+to delete and type Backspace or Delete.  Alternatively, you can type new
+text, in which case it will replace the selected text.
+
+6. Copy the selection. To copy the selection into this window, select
+what you want to copy (either here or in another application), then
+click button 2 to copy the selection to the point of the mouse cursor.
+
+7. Edit.  Text widgets support the standard Motif editing characters
+plus many Emacs editing characters.  Backspace and Control-h erase the
+character to the left of the insertion cursor.  Delete and Control-d
+erase the character to the right of the insertion cursor.  Meta-backspace
+deletes the word to the left of the insertion cursor, and Meta-d deletes
+the word to the right of the insertion cursor.  Control-k deletes from
+the insertion cursor to the end of the line, or it deletes the newline
+character if that is the only thing left on the line.  Control-o opens
+a new line by inserting a newline character to the right of the insertion
+cursor.  Control-t transposes the two characters on either side of the
+insertion cursor.
+
+7. Resize the window.  This widget has been configured with the "setGrid"
+option on, so that if you resize the window it will always resize to an
+even number of characters high and wide.  Also, if you make the window
+narrow you can see that long lines automatically wrap around onto
+additional lines so that all the information is always visible.}

+# pressX -		X-coordinate at which the mouse button was pressed.

+# Elements of tkPriv that are used in this file:
+#
+# cursor -		Saves the -cursor option for the posted menubutton.
+# focus -		Saves the focus during a menu selection operation.
+#			Focus gets restored here when the menu is unposted.
+# grabGlobal -		Used in conjunction with tkPriv(oldGrab):  if
+#			tkPriv(oldGrab) is non-empty, then tkPriv(grabGlobal)
+#			contains either an empty string or "-global" to
+#			indicate whether the old grab was a local one or
+#			a global one.
+# inMenubutton -	The name of the menubutton widget containing
+#			the mouse, or an empty string if the mouse is
+#			not over any menubutton.
+# menuBar -		The name of the menubar that is the root
+#			of the cascade hierarchy which is currently
+#			posted. This is null when there is no menu currently
+#			being pulled down from a menu bar.
+# oldGrab -		Window that had the grab before a menu was posted.
+#			Used to restore the grab state after the menu
+#			is unposted.  Empty string means there was no
+#			grab previously set.
+# popup -		If a menu has been popped up via tk_popup, this
+#			gives the name of the menu.  Otherwise this
+#			value is empty.
+# postedMb -		Name of the menubutton whose menu is currently
+#			posted, or an empty string if nothing is posted
+#			A grab is set on this widget.
+# relief -		Used to save the original relief of the current
+#			menubutton.
+# window -		When the mouse is over a menu, this holds the
+#			name of the menu;  it's cleared when the mouse
+#			leaves the menu.
+# tearoff -		Whether the last menu posted was a tearoff or not.
+#			This is true always for unix, for tearoffs for Mac
+#			and Windows.
+# activeMenu -		This is the last active menu for use
+#			with the <<MenuSelect>> virtual event.
+# activeItem -		This is the last active menu item for
+#			use with the <<MenuSelect>> virtual event.
+#-------------------------------------------------------------------------
+
+#-------------------------------------------------------------------------
+# Overall note:
+# This file is tricky because there are five different ways that menus
+# can be used:
+#
+# 1. As a pulldown from a menubutton. In this style, the variable 
+#    tkPriv(postedMb) identifies the posted menubutton.
+# 2. As a torn-off menu copied from some other menu.  In this style
+#    tkPriv(postedMb) is empty, and menu's type is "tearoff".
+# 3. As an option menu, triggered from an option menubutton.  In this
+#    style tkPriv(postedMb) identifies the posted menubutton.
+# 4. As a popup menu.  In this style tkPriv(postedMb) is empty and
+#    the top-level menu's type is "normal".
+# 5. As a pulldown from a menubar. The variable tkPriv(menubar) has
+#    the owning menubar, and the menu itself is of type "normal".
+#
+# The various binding procedures use the  state described above to
+# distinguish the various cases and take different actions in each
+# case.

+# Elements of tkPriv that are used in this file:
+#
+# afterId -		If non-null, it means that auto-scanning is underway
+#			and it gives the "after" id for the next auto-scan
+#			command to be executed.
+# char -		Character position on the line;  kept in order
+#			to allow moving up or down past short lines while
+#			still remembering the desired position.
+# mouseMoved -		Non-zero means the mouse has moved a significant
+#			amount since the button went down (so, for example,
+#			start dragging out a selection).
+# prevPos -		Used when moving up or down lines via the keyboard.
+#			Keeps track of the previous insert position, so
+#			we can distinguish a series of ups and downs, all
+#			in a row, from a new up or down.
+# selectMode -		The style of selection currently underway:
+#			char, word, or line.
+# x, y -		Last known mouse coordinates for scanning
+#			and auto-scanning.
