*
* NOTE: The `zone.js` package is not built as part of `package-builder`'s `buildTargetPackages()`
* nor is it copied into the same directory as the Angular packages (e.g.
* `dist/packages-dist/`) despite its source's being inside `packages/`, because it is not
* published to npm under the `@angular` scope (as happens for the rest of the packages).

* @param {string} destPath Path to the output directory into which we copy the npm package.
* This path should either be absolute or relative to the project root.
