title: Graph of included files
body: <p>When I work on someone else's code, I tipically need to abuse of grep in order to find data types declarations etc, and this usually makes me confused.</p>
  
  <p>I'd like to have some tool which analyzes the source code and produces some graphviz-like drawing and allows me to follow dependencies.</p>
  
  <p>Also I've found <a href="http://www.kernel.org/pub/linux/kernel/people/rayl/headergraphs/" rel="nofollow noreferrer">this</a> on the internet, but I think is taylored for the linux kernel only.</p>
