94# 	name        Directory name of continent/ocean as it appears in
95# 	            _PATH_ZONEINFO.
96# 	title       Menu text of this continent/ocean to be displayed in the
97# 	            continent-selection menu.
98# 	nitems      Number of submenu items associated with this
99# 	            continent/ocean.
100# 	tlc_N       2-character country code of the Nth submenu item associated
101# 	            with this continent displayed in the country-selection menu
102# 	            (which appears after continent selection).
