title: Absolute vs. relative paths
body: <p>If I use absolute paths, I can't move the whole directory to a new location.
  If I use relative paths, I can't move individual files to new locations.</p>
  
  <p>What's the solution here? Do you set up a config file that holds the root path and go from there? Or do you have a rule like: Never move files around?</p>
  
  <p>I've seen in some projects that people use dirname(<strong>FILE</strong>). What is the point of that, I mean, why not simply leave it out since the dirname is relative anyway (depending on where the file sits)?</p>
