# This script is reponsible for talking to rpkid and populating the
# portal-gui's sqlite database. It asks rpkid for the list of received
# resources, and the handle's of any children.
#
# This script takes optional arguments, which are the handles of the <self/> we
# are asking about. If rpkid is hosting several resource handles, this script
# should be invoked with an argument for each hosted handle.
