title: Preload script file
body: <p>There are numerous plug-ins to preload images, but is there a way to preload javascript? My application uses a big js file and it take about 5 seconds or so to load before the page shows... so, is there a way I can display a "loading message" while I somehow preload the script? (A sort of 'Loading...' like in Gmail)</p>
  
  <p>Thanks</p>
