{{#invoke:Language/data/ISO 639-2/make|ISO_synonym_extract|file-date=2013-01-11}}

reads a local copy of data from the table at http://www.loc.gov/standards/iso639-2/php/English_list.php, extracts
the ISO 639-2 (or 639-2T) codes that have equivalent ISO 639-1 codes and creates a table to translate 639-2 to 639-1.
ISO-639-3 uses 639-2T codes

useful lines in the source table have the form:
	<English name>\t<all English names>\t<all French names>\t<639-2 code>\t<639-1 code>\n
where:
	<English name> is primary English name (not used here); one of <all English names> so duplicates code listing
	<all English names> is all of the English names (not used here)
	<all French names> is all of the French names (not used here)
	<639-2 code> is the three-character ISO 639-2 or 639-2B/639-2T language code; when 639-2T present, use that code
	<639-1 code> is the two-character ISO 639-1 language code synonym of the -2 code (if one is defined)
		
	like this (with synonym):
		Abkhazian	Abkhazian	abkhaze	abk	ab
	or (without synonym):
		Achinese	Achinese	aceh	ace	 

for the file date use the date listed at the bottom of the source page in yyyymmdd numeric format without hyphens or spaces
