Advanced Usage
--------------
The application template is evaluated in the context of a
`Rails::Generators::AppGenerator` instance. It uses the `apply` action
provided by
[Thor](https://github.com/erikhuda/thor/blob/master/lib/thor/actions.rb#L207).
This means you can extend and change the instance to match your needs.
For example by overwriting the `source_paths` method to contain the
location of your template. Now methods like `copy_file` will accept
relative paths to your template's location.
```ruby
def source_paths
[File.expand_path(File.dirname(__FILE__))]
end
```
