title: How to use 'NeedsTeXFormat{}' Option
body: <p>So I am trying to understand how <code>\NeedsTeXFormat{LaTeX2e}</code> is actually used. All the documentation I can find basically says to add a date after the <code>\NeedsTeXFormat{LaTeX2e}</code> with <code>[]</code> however, I cannot figure out if there is any other option for <code>\NeedsTeXFormat{}</code> for using the newer <code>LaTeX3</code> items.</p>
  <p>I am trying to teach myself how to write a class by updating my university's thesis class since it is about 8 years out of date and is using some packages that are deprecated and broken.</p>
