title: Build a App that accepts language pack
body: <p>I'm quite lost here and I need guidance.</p>
  
  <p>I need to build a web app that will support language packs... the idea is to start with a default language such as English, and then the client will be able to download a language pack and install it and then choose between the default language and any other installed language. Are there any patterns on the matter? Maybe a open source software I could study (and take as an example)? Or maybe some literature on it?</p>
  
  <p><strong>Edit1:</strong> The idea here is that the user will deploy the web app on premises (or cloud IaaS) and install as many language packs as are available, and the app would check the browser language and check if there's a compatible language pack to translate to... .Net already does that using localized resources files, that require recompilation...</p>
