title: AppEngine dev_appserver.py not showing any outputs
body: <p>I installed Python2.6 and Google App Engine (GAE). </p>
  
  <p>I realized that GAE does not run on 2.6, so I installed 2.5 as well.</p>
  
  <p>Now I have a very basic code as follows and it does not show on the localhost:8080</p>
  
  <p>I typed the following in cmd.exe under my dir testapps.</p>
  
  <p>c:\Users\myname\testapps>"\Program Files\Google\google_appengine\dev_appserver.py" helloworld</p>
  
  <p>I am hoping someone lead me to the right direction.</p>
