# A bbclass to handle installed GSettings (glib) schemas, updated the compiled
# form on package install and remove.
#
# The compiled schemas are platform-agnostic, so we can depend on
# glib-2.0-native for the native tool and run the postinst script when the
# rootfs builds to save a little time on first boot.

# TODO use a trigger so that this runs once per package operation run
