# tzsetup objects (fatally) if any entry in zone.tab or zone1970.tab
# refers to a country code that doesn't exist in misc/iso3166. While
# arguably that should be fixed, for compatibility we remove such
# entries here to avoid the problem.
#
# This used to be done by adding patch files for each country to
# remove, but that doesn't work for zone1970.tab.
#
# We generate a list of all 2-letter codes that are NOT in iso3166;
# then, for any entry in zone.tab or zone1970.tab that contains a bad
# code: first emit a commented-out version of the line, then a version
# with the bad codes stripped out of the first field (unless this
# leaves the first field empty).

# check-plist is too lenient for us; it doesn't care if there are
# files in the stage dir that are commented out in plist due to port
# options. But we need to check for an exact match, otherwise the
# final package may be incorrect if entries move into or out of the
# "backward" file.
#
# So this rule makes the additional check that there must be no file in
# STAGEDIR not accounted for by .plist-files-no-comments.
