Oh yeh, this script is REALLY REALLY old. I wrote it even before this site was even in existence. I'm sure it could use some sprucing up from the technical level in addition to all the new-fangled items such as the runic atlas. In all honestly, I never really considered this script finished, but if it gives people a starting point, then at least it still has some use.
I haven't even looked into the runic atlases yet. Probably not a terrible job, but nothing small either.
