Very nice! I'll study this til I know the exact purpose of every line.
I already learned I was wrong about there being no functions in tcl.

A couple comments: In your README.md you comment that it requires wish
8.6, but you can change it to 8.5 or 8.4. The place I changed it to get
it to work was in the following totd.tcl line near the top:

exec wish8.5 "$0" "$@"

But the following line from cwindef.tcl had no effect:

set	Wish		/usr/local/bin/wish8.4

That's probably because my computer has no /usr/local/bin/wish*, but
instead has /usr/bin/wish and /usr/bin/wish8.4 and /usr/bin/wish8.5.

In README.md, you might want to document those two lines a bit more.

Also, I had no $TCLINC environment variable, so in order to run your
program I had to:

export TCLINC /d/at/tcl/totd-master

The other thing is, I made a copy of your totd shellscript, put it on
the path, and added the following:

cd /d/at/tcl/totd-master

So that it would start in the directory containing all the tcl files.

I have a question:

Why did you decide to make the field that displays the fortune
read-write instead of read-only?

Jesse, I really want to thank you for this. I've been trying for 15
years to understand tcl/tk, and have been held back by well written,
clean examples. Your code provides me with just what I need.

Thanks,
