I’ve exceeded my quota on a cluster, for the number of files allowed in my shared group directory.

I noticed from the Package docs that all installed packages are downloaded into `.cache/` within Pkg.dir. Is there any harm in nuking this periodically? And will it get filled up behind my back, outside of `Pkg.add()` calls?

This is using Pkg2, on Julia 0.6.

Check this out. Might have used the word `nuclear`, too 😛

Ah, but that’s the precompile cache, in `.julia/lib`. I’m talking about the stuff in `.julia/.cache`.

But I like your approach. Remember, always nuke it from orbit, it’s the only way to be sure.
