This directory will contain hello-world examples in gtk2, gtk3, and - since 
as of September 2022 - gtk4.

The reason why this directory was created in August 2020 was because I needed 
a quick way to test the installation on the windows platform specifically (e. 
g. in a WSL1 or WSL2 environment), and I did not want to copy/paste an example 
from the www - in particular when there was no working internet connection 
available. So an offline solution had to exist.

Thus, I added this directory to the gtk_paradise gem.
