+vzic A program to convert the IANA (formerly Olson) timezone
+database files into VTIMEZONE files compatible with the iCalendar
+(RFC5445) and TZDIST (RFC7808) specifications
+
+This is vzic, a program to convert the IANA (formerly Olson) timezone
+database files into VTIMEZONE files compatible with the iCalendar
+specification (RFC2445).
+
+(The name is based on the zic program which converts the IANA files
+into time zone information files used by several Unix C libraries,
+including glibc. See zic(8) and tzfile(5).)
+
+The vzic software is licensed according to the terms of the GNU
+General Public License version 2.0 or later (see
+LICENSES/GPL-2.0-or-later.txt). The IANA timezone database files are
+in the public domain.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
