// The bundled `nupkgs` folder normally lives on disk next to this module. But when this

// snapshot-only path (e.g. `/snapshot/...`) that only the packaged Node process itself can
// read. `dotnet restore` runs as a separate OS process and can't see into that snapshot at
// all, so instead of pointing nuget.config there directly, we copy the offline packages
// into the same real, on-disk directory generator.generate() already created below for
// Parse.csproj/Program.cs, and point nuget.config at that.
