Thoughts on DRYing this up, something along the lines of:
```ruby
require suspenders_file_path('generators', 'app_generator')
require suspenders_file_path('actions')
require suspenders_file_path('app_builder')

...

def suspenders_file_path(*args)
  File.expand_path(File.join('..', 'lib', 'suspenders', *args), File.dirname(__FILE__))
end
```
