 libportal provides GIO-style C APIs for most Flatpak portals' D-Bus
 interfaces. It is primarily intended for installation in Flatpak runtimes,
 where applications can use it to interact with portals; it can also be
 used to test the portal services.

 See the xdg-desktop-portal package's description for more information
 about portals.

 This package can be used by other packages using the GIRepository format
 to generate dynamic bindings for GTK 4 integration.
