Ah! I had a look at the source code for `Pkg.init` and see that its default first argument is DEFAULT_META, which is initialized to "git://github.com/JuliaLang/METADATA.jl". So `Pkg.init` is used to point the package manager to the global METAFILE package directory. This is definitely not what I took away from the documentation, which reads:
help?> Pkg.init Base.Pkg.init() Initialize "Pkg.dir()" as a package directory. This will be done automatically when the "JULIA_PKGDIR" is not set and "Pkg.dir()" uses its default value. This is the same as the online docs. Since the documentation talks about `Pkg.dir()` I thought it was for establishing the local package repository location. Looks like the documentation wrong/out of date? Thanks, --Peter
