This directory may contain code that may serve as "examples", ideally simple
examples, but more advanced examples can be stored here as well.

The difference between files stored in the directory here, and files stored
in the subdirectory gtk_paradise/widgets/ is that the latter may tap into
code that is available within the gtk_paradise project itself, whereas the
former MUST contain only self-contained examples that work, by default,
with ruby-gtk2 or ruby-gtk3 only. That way we can see which examples work,
and which ones that were modified via the gtk_paradise project do not work.
The user may thus learn from the "raw" examples as well.

In October 2020 the above rule was a bit relaxed; while it still applies
to gtk2, I try to shorten the code in the gtk3-examples sometimes, to see
whether it is simpler to maintain it, or more confusing - we will see.
The subdirectory advanced/ may contain code that taps into the gtk_paradise
more determinedly so.

In November 2023 the code in this directory is now deprecated. I will,
however had, retain it for the time being, if only for others to learn
from it, or perhaps even see someone else maintain the ruby-gtk2
bindings.
