# Consolidated patchfile, based on GitLab/fhgwright/ntpsec
#
# This diff is from NTPsec_1_2_4 vs. macports-1_2_4
#
# The patches are reduced from earlier versions, based on using legacy-support
# to provide some missing features.  Some patches are still needed, though,
# to accommodate OS versions <10.13 (plus a Python 2 fix in ntpq).
