// Warning! This is a magical import. We don't want to have multiple copies of
// typescript.d.ts around the repo, there's already one in
// deno_typescript/typescript/lib/typescript.d.ts. Ideally we could simply point
// to that in this import specifier, but "cargo package" is very strict and
// requires all files to be present in a crate's subtree.
