<div dir="ltr">While something like a SimFactory 3 based system might be the best in the long run, I think Ian's proposed download.sh system would be nice incremental improvement on the existing ExternalLibraries system. It allows us to have minimal changes to the existing mostly-working system, but with the added benefit of not having large files around when not necessary. For that reason alone, I think it would be good to implement it in the short to mid term, until something better is ready.</div>
