I maintain a starter kit that bundles a Yarn yarn.lock file.
Now that NPM v5 is released and recommends committing its own package-lock.json, I'd like to include both.
Is it possible to generate both files without actually installing anything, solely for the purpose of committing the locks?
Note: The reason for including both is that, as a starter kit, the end-user may choose to use Yarn or NPM. I have no control over their environment, so I'd like to support both out-the-box.
