+#### onlyCompileBundledFiles *(boolean) (default=false)*

+The default behavior of ts-loader is to act as a drop-in replacement for the `tsc` command,
+so it respects the `include`, `files`, and `exclude` options in your `tsconfig.json`, loading
+any files specified by those options. The `onlyCompileBundledFiles` option modifies this behavior,
+loading only those files that are actually bundled by webpack, as well as any `.d.ts` files included
+by the `tsconfig.json` settings. `.d.ts` files are still included because they may be needed for
+compilation without being explicitly imported, and therefore not picked up by webpack.
