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: \t\t\t<639-2 code>\t<639-1 code>\n where:  is primary English name (not used here); one of  so duplicates code listing  is all of the English names (not used here)  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
