OK, it is available at github now:
https://github.com/ngtk3
No nimble install yet, I will try to read the nimble chapter of Dominiks book
soom, so maybe it will become possible...
The toy chess is available, and a minimal test for each of the ten wrappers.
Next task may be to add the missing C glib/gobject macros, so that all the C
examples like application10 can be transfered directly to Nim.
For example, to try the toychess for Linux you may execute these commands:
```code
cd
mkdir ngtk3
cd ngtk3
git clone https://github.com/ngtk3/common
git clone https://github.com/ngtk3/nim-atk
git clone https://github.com/ngtk3/nim-cairo
git clone https://github.com/ngtk3/nim-chess
git clone https://github.com/ngtk3/nim-gdk3
git clone https://github.com/ngtk3/nim-gdk_pixbuf
git clone https://github.com/ngtk3/nim-gio
git clone https://github.com/ngtk3/nim-glib
