There are estimated to be in the order of five to six thousand languages in common use today. There is no way I can supply all these with the system. So I have provided a few sample languages. The GraRLS language specification gives details of the format of the file. I have also provided a GraRLS program ( "langtest.grs" ) along with a batch file ( "langtest.bat" ) for testing the language files you create - look at the comment at the top of the program.
In the future I may start hosting a collection of user supplied language files.
