Viking is currently dual managed - with a corresponding Github presence at: https://github.com/viking-gps/viking Where you may find it easier to view the code and raise issues there too.

Grammar-multi is most useful for languages which words have many forms («more» inflected languages), and for which grammatical agreement (and other syntactic connections) in a sentence is «more» important and «obvious». Need a help of linguists. Program is not for every-day use, but to show Grammar is working. If you want your language Grammar version - tell me.
