Adding functionality to an app in modular fashion?

Building a Rails app entails creating files in multiple locations.
Config
dir, App, Views, Layouts, etc.

If I have an existing application app framework, is there a way to add a
new feature (for example, contracts management) where the files
for the new feature are bundled together and not scattered willy-nilly
throughout the Rails application directory tree?

Pros? Cons?

Thanks,

Joe

Build it as a Rails engine, so that it is its own application but can be
included into your new applications.

The pros and cons are only something you can come up with.
