title: What is a .Spritefont file, and how do I create it?
body: <p>I have looked for them for half an hour. I have a .TFF font, I have a .png spritesheet, I have everything I need to be able to write down any sort of string, but apparently I need  to load content in XNA as <code>userfont = Content.Load&lt;SpriteFont&gt;</code> </p>
  
  <p>And this .SpriteFont filetype I can't find. Help! </p>
