Wrong filenames in src/package.json?

In the template for `src/package.json`, you have these lines:

```
  "module": "<%= props.libraryName.kebabCase %>.js",
  "jsnext:main": "<%= props.libraryName.kebabCase %>.js",
  "typings": "<%= props.libraryName.kebabCase %>.d.ts",
```

but, in the output to `dist/`, these files are all named `index` rather than the library name. Or have I misunderstood something?
