[org.gnome.Boxes.json](https://gitlab.gnome.org/GNOME/gnome-boxes/blob/master/build-aux/flatpak/org.gnome.Boxes.json):

Boxes VMs to show up in the GNOME Shell search results. See the [GNOME documentation for "Search 
Providers"](https://developer.gnome.org/SearchProvider/).
   * gtk-style.css: contains our overwrites in the toolkit theme and Boxes-specific CSS style classes.
