# This is used to create unique IDs for each VTIMEZONE component.
# The prefix is put before each timezone city name. It should start and end
# with a '/'. The first part, i.e. 'myorganization.org' below, should be
# a unique vendor ID, e.g. use a hostname. The part after that can be
# anything you want. We use a date and version number for libical. The %D
# gets expanded to today's date. There is also a vzic-merge.pl which can be
# used to merge changes into a master set of VTIMEZONEs. If a VTIMEZONE has
# changed, it bumps the version number on the end of this prefix. */

# This is used to indicate how timezone aliases (indicated by a Link line

# This indicates if top-level timezone aliases (a timezone name without
# any '/' such as "EST5EDT") should be ignored. If 0, a VTIMEZONE is

# an effect if CREATE_SYMLINK is 0, and mainly is useful for backward
# compatibility with previous vzic versions.
