- * @fileoverview Prepends a TypeScript reference comment to the beginning of a file.
- * This is necessary because JSR requires that all JavaScript files have a reference
- * to the TypeScript types file. We can't do this in Rollup because that happens
- * before tsc is run. This script is run after tsc is run.
- *
- * Usage:
- *  node tools/prepend-type-ref.js filename.js
