title: Code Igniter Update Engine
body: <p>I am planning to develop a pretty awesome new web app that has a one time fee including free updates of 1.X updates (X being the update).</p>
  
  <p>I don't want to get people to download a new version and install it manually as it can be a real pain for some people, also it's bad if there is an important bug that needs fixing and people don't update.</p>
  
  <p>The app will be built with Code Igniter so I was looking for some kind of integrated system that allowed me to send out updates for the web app?</p>
