-// usage: java ZoneCompiler <setup file> <data directory> <output directory> <tzdata version>
-//
-// Compile a set of tzfile-formatted files into a single file containing an index.
-//
-// The compilation is controlled by a setup file, which is provided as a
-// command-line argument.  The setup file has the form:
-//
-// Link <toName> <fromName>
-// ...
-// <zone filename>
-// ...
-//
-// Note that the links must be declared prior to the zone names.
-// A zone name is a filename relative to the source directory such as
-// 'GMT', 'Africa/Dakar', or 'America/Argentina/Jujuy'.
-//
-// Use the 'zic' command-line tool to convert from flat files
-// (such as 'africa' or 'northamerica') to a directory
-// hierarchy suitable for this tool (containing files such as 'data/Africa/Abidjan').
