You're referring to the process of internationalization, which is usually treated as a separate process from localization. Internationalization is making it possible to swap out language-specific assets at runtime (which is what Lars points to as the difficult part of this which can be carried over to other projects); localization is the process of actually making those language-specific assets. Internationalization is done by spending (usually in-house) programmer time; localization is about throwing money at (usually outsourced) translators.
