Traditionally IANA has distributed their timezone data in pure source form, replete with extensive historical comments. As of release 2017c, they've added a compact single-file format that omits comments and abbreviates command keywords. This form is way shorter than the pure source, even before considering its allegedly better compressibility. Hence, let's distribute the data in that form rather than pure source. I'm pushing this now, rather than at the next timezone database update, so that it's easy to confirm that this data file produces compiled zic output that's identical to what we were getting before.
