# Common code for systemd based services.
#
# Prior to inheriting this class, recipes can define services like this:
#
# SYSTEMD_SERVICE_${PN} = "foo.service bar.socket baz@.service"
#
# and these files will be added to the main package if they exist.
#
# Alternatively this class can just be inherited and
# ${PN}.service will be added to the main package.
