+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 on your path
+then you can invoke any of the programs in this directory just
+by typing its file name to your command shell under Unix.  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.
+
+rolodex -	A mock-up of a simple rolodex application.  It has much of
+		the user interface for such an application but no back-end
+		database.  This program was written in response to Tom
+		LaStrange's toolkit benchmark challenge.
+
+tcolor -	A color editor.  Allows you to edit colors in several
+		different ways, and will also perform automatic updates
+		using "send".
+
+rmt -		Allows you to "hook-up" remotely to any Tk application
+		on the display.  Select an application with the menu,
+		then just type commands:  they'll go to that application.
+
+timer -		Displays a seconds timer with start and stop buttons.
+		Control-c and control-q cause it to exit.
+
+browse -	A simple directory browser.  Invoke it with and argument
+		giving the name of the directory you'd like to browse.
+		Double-click on files or subdirectories to browse them.
+		Control-c and control-q cause the program to exit.

+# Keith Vetter 2003-03-21: this started out as a simple little program
+# but was so much fun that it grew and grew. So I apologize about the
+# size but I just couldn't resist sharing it.
+#
+# This is a whizzlet that does a Rube Goldberg type animation, the
+# design of which comes from an New Years e-card from IncrediMail.
+# That version had nice sound effects which I eschewed. On the other
+# hand, that version was in black and white (actually dark blue and
+# light blue) and this one is fully colorized.
+#
+# One thing I learned from this project is that drawing filled complex
+# objects on a canvas is really hard. More often than not I had to
+# draw each item twice--once with the desired fill color but no
+# outline, and once with no fill but with the outline. Another trick
+# is erasing by drawing with the background color. Having a flood fill
+# command would have been extremely helpful.
+#
+# Two wiki pages were extremely helpful: Drawing rounded rectangles
+# which I generalized into Drawing rounded polygons, and regular
+# polygons which allowed me to convert ovals and arcs into polygons
+# which could then be rotated (see Canvas Rotation). I also wrote
+# Named Colors to aid in the color selection.
+#
+# I could comment on the code, but it's just 26 state machines with
+# lots of canvas create and move calls.

+#	Calculate a Knight's tour of a chessboard.
+#
+#	This uses Warnsdorff's rule to calculate the next square each
+#	time. This specifies that the next square should be the one that
+#	has the least number of available moves.
+#
+#	Using this rule it is possible to get to a position where
+#	there are no squares available to move into. In this implementation
+#	this occurs when the starting square is d6.
+#
+#	To solve this fault an enhancement to the rule is that if we
+#	have a choice of squares with an equal score, we should choose
+#	the one nearest the edge of the board.
+#
+#	If the call to the Edgemost function is commented out you can see
+#	this occur.
+#
+#	You can drag the knight to a specific square to start if you wish.
+#	If you let it repeat then it will choose random start positions
+#	for each new tour.
