-# This file contains a table with the following columns:
-# 1.  ISO 3166 2-character country code.  See the file `iso3166.tab'.
-#     This identifies a country that overlaps the zone.  The country may
-#     overlap other zones and the zone may overlap other countries.
-# 2.  Latitude and longitude of the zone's principal location
+# This file contains a table where each row stands for an area that is
+# the intersection of a region identified by a country code and of a
+# zone where civil clocks have agreed since 1970.  The columns of the
+# table are as follows:
+#
+# 1.  ISO 3166 2-character country code.  See the file 'iso3166.tab'.
+# 2.  Latitude and longitude of the area's principal location
 #     in ISO 6709 sign-degrees-minutes-seconds format,
 #     either +-DDMM+-DDDMM or +-DDMMSS+-DDDMMSS,
 #     first latitude (+ is north), then longitude (+ is east).
-#     This location need not lie within the column-1 country.
 # 3.  Zone name used in value of TZ environment variable.
 #     Please see the 'Theory' file for how zone names are chosen.
+#     If multiple zones overlap a country, each has a row in the
+#     table, with column 1 being duplicated.
 # 4.  Comments; present if and only if the country has multiple rows.
 #
 # Columns are separated by a single tab.
 # The table is sorted first by country, then an order within the country that
 # (1) makes some geographical sense, and
