# The vast majority of the DVB scan files contained in this repository
# are DVBv3 scan files. This format has been deprecated in favor of the
# DVBv5 scan format.
#
# Use this makefile to convert the existing DVBv3 scan files to DVBv5
# scan files until such time as DVBv5 scan format is in widespread use.
#
# Requires dvb-format-convert from v4l-utils.
