This tool generates the tzlookup.xml file from the countryzones.txt (proto text) file. tzlookup.xml is used to associate zones with regions/countries. The tool uses ICU4J and IANA data to synthesize some time zone metadata. Besides tzlookup.xml, the tool also generates a tzids.prototxt file containing information about zone IDs, id links and "functionally identical" zones[1] within each known country. These can be used to map time zone IDs to Android's preferred set. This duplicates information from the tzlookup.xml, but it is easier to use from host tools than Android's tzlookup.xml's format. [1] i.e. zones that differed in the past but were "folded in" to other zones and are not distinct for future times according to IANA or ICU/CLDR.
