title: Sphinx docs variable
body: <p>I'm writing documentation for a new project using <code>Sphinx</code></p>
  
  <p>But because this project is new, its name may change and I don't want to replace all reference of "Project Name" in all my documentation.</p>
  
  <p>So I want to know if there is a way to put some variable/constant on <code>Sphinx</code> to do that.</p>
  
  <p>I know there is a <code>i18n</code> feature on <code>Sphinx</code>, so I can use gettext to change the "Project Name" without something else. But I'm looking for a proper way to do that.</p>
