This is an AboutDialog, reading its text from
src/tcoda/demo/about.txt.

The five lines above are a fixed header. The
rest is the body, which scrolls once it grows
past ten lines, as this one does.

The version in the header is a $$version
placeholder, filled in through
AboutMenuItem(variables=...).

Everything in this demo is ordinary consumer
code: read src/tcoda/demo/ to see how each widget
and dialog is used.

Press escape to close.
