title: Import python package from local directory into interpreter
body: <p>I'm developing/testing a package in my local directory. I want to import it in the interpreter (v2.5), but sys.path does not include the current directory. Right now I type in <code>sys.path.insert(0,'.')</code>. Is there a better way? </p>
  
  <p>Also, </p>
  
  <pre><code>from . import mypackage
  </code></pre>
  
  <p>fails with this error:</p>
  
  <pre><code>ValueError: Attempted relative import in non-package
  </code></pre>
