title: How can I generate with Sphinx a complex documentation website for 3 projets
body: <p>I would like to be able to generate an internal documentation website for all our projects using sphinx.</p>
  
  <p>Let's say I have 3 main projects in my company (let's call them <em>Todo</em>, <em>Receipes</em> and <em>Calendar</em> for instance). I would like to build <strong>one</strong> site for all, but to be able to change colors/logo for every sub-projet (<em>Todo</em> would be blue, <em>Receipes</em> green and <em>Calendar</em> pink) so our readers always know what they are reading. </p>
  
  <p>I would like to make one site becauseI want to be able to make search in all 3 projects at once.</p>
  
  <p>The main page of the site would consist of the list of the 3 projets and a search field.</p>
  
  <p>Any idea to do this with sphinx ?</p>
