I noticed that Virgil got the arctic code vault badge, and thought it was funny, but I never checked what the conditions or criteria were. So I looked.
> The snapshot consists of the HEAD of the default branch of each repository, minus any binaries larger than 100KB in size. (Repos with 250+ stars retained their binaries.) Each was packaged as a single TAR file.
Virgil bootstraps from compiler binaries checked into the repo--there is literally no other way to get a PL off the ground without a compiler or interpreter binary in some language another computer understands--so I guess the archive has a completely useless source-only copy. That is, unless future historians want to write a new interpreter in order to run the source that's checked in :D
