Review of    Main reasons for No langbox seem to be dab pages and redirects to Spurious languages No idea yet what to do about these  stand by  I suppose you intend to fix the One ISO code and mismatching glottocodes  Mismatching ISO code  No ISO code entries by hand I dont think a bot could decide which codes are the correct ones  Multiple ISO codes but no glottocode The longest section The bot could add glottocodes to pages where everything fits together eg lines  Bobo language both ISO codes appear in your list under the correct language name so nort and sout could be added or even to those where only part of the data fit eg lines  Bontoc language add cent and cent but not fina as the corresponding ISO code isnt in the langbox Dont expect me to code this very quickly  Multiple ISO codes and mismatching missing or surplus glottocodes Will filter this section in the next run ie entries where all codes are matching should be removed by the bot Again please be patient
