Yes, that's why I added the hashes of the original files for Arthur. I 
don't know how to re-create the blorb currently, but if we do figure out 
how to do it then we'll already have the appropriate information... So 
for now we can only use the downloaded file, but that seems reasonably 
safe to me since we check the download against the known hashes. (I 
checked the contents of the blorbs and as far as I can determine there's 
nothing dodgy.)

Incidentally, for Z-code games requiring Zoom, shouldn't the resulting 
packages depend on zoom-player rather than just recommending it? I know 
we usually just recommend engines, but I'm not sure that's always 
appropriate.

Regards,

Stephen
