title: Proper way to include a jQuery library
body: <p>I am working on a module for Drupal 7. I am using some of the jQuery UI modules which are included. </p>
  
  <p>my natural way to include these is to use <code>drupal_add_js()</code> and <code>drupal_add_css()</code> with the relevant files. However this feels a little wrong. Is there an official (or better) way to include these libraries, either from Drupal or jQuery.</p>
  
  <p>I tend to find the Drupal/jQuery interface very powerful but frustratingly sparse on documentation.</p>
