title: Confused with symfony2 bundles
body: <p>I am little bit confused with symfony2 bundles.</p>
  
  <p>I want to know that does everything in symfony is bundle including main application.</p>
  
  <p>I was thinking as Core of site is somewhere i can write code to use bundles like we use plugins from main application code.</p>
  
  <p>Or there is no core thing in Symfony . The core itself will be bundle</p>
