Background
I have a build process that copies JavaScript source files to certain locations.
I can then run it with Node.js.
However, when debugging with VSCode, it doesn't understand the relationship between the source files and the runtime files (and it's more complicated than a single remoteRoot).
Question
My proposed solution is to use a source map to map back to the original file.
How can I make a source map with identical content mapping, but just a change in the file path?
