title: make qt distribution neat. remove part of dll?
body: <p>I made a qt program on windows. 
  And I want to share with my friend.
  but my friend use pure windows 7.</p>
  
  <p>it would be nice if I can include only dll needed.
  and it would be much nicer if I can remove part of dll which are unused.
  (to reduce size of dll)</p>
  
  <p>how can I do this? thanks</p>
