#!/bin/sh

# A hook script to update the D-Bus API signature database every time a release
# tag is pushed. See the git-hooks documentation for the parameters it’s called
# with. See $(top_srcdir)/dbus-deviation.mk for more information about how this
# project uses dbus-deviation to check D-Bus API stability.
#
# If the API signature database is updated, a git note will be added to the new
# tag for each D-Bus API in the project, and the notes will be pushed remotely.
