title: Xcode: How to set current working directory to a relative path for an executable?
body: <p>I have a command-line executable in Xcode.</p>
  
  <p>I am using Xcode 5.1. In the "Scheme Editor" for the project under "Options" there is an option for "Working Directory". How can I specify a path relative to the .xcodeproj file? I have tried a single period.</p>
  
  <p>I need this because the code needs to assume the existence of  files relative to the project directory.</p>
