Is there a clean, recomended way to access the mountpath from inside a template, so an express app can be run both standalone and as a part of another app (by means of app.use), with the paths pointing to the correct destination either way?

Something like:

```
{{mountpath}}route/to/file

```

So in the case that the app is running standalone, mountpath will be `/`, and in case is running as a submodule, mountpath could be `/foo/` 

Note: I'm using handlebars.
