MarsSeed [1] filed a deletion request for isl16 [2]: This legacy version from 2016 has its source deleted (404). But it seems it is not needed specifically by anything in AUR. So I recommend to delete this if there are no objections. There are no user votes or comments that would indicate that anyone would protest.
