Guile-GI is a Guile package that hopes to provide access for
GObject-based libraries such as GTK+, GLib, WebKitGTK+ and many more.

It supports GNU/Linux, and has been tested with Guile-2.2 and
Guile-3.0. Guile GI is licensed under the GPL3+. This
documentation is licensed under the FDLv1.3+.

If you want to write a Guile application for GNOME or a Guile GUI
application using GTK+, then Guile-GI (when it is finished) will be
the way to go.
