title: ExpressJS app generator not recognizing its flags
body: <p>I can't run the express app generator with flags.<br>
  See example below. I run <code>express --version</code> and it interpretes the --version part as a target directory and creates the app there. In Windows XP SP3.<br>
  Am I doing something wrong? My knowledge is really very limited.  </p>
  
  <pre><code>X:\server&gt;node --version
  v0.8.6   
  
  X:\server&gt;express --version
  
     create : .
     create : ./package.json
     create : ./app.js
     create : ./public
     create : ./public/javascripts
     create : ./public/images
     create : ./public/stylesheets
     create : ./public/stylesheets/style.css
     create : ./routes
     create : ./routes/index.js
     create : ./routes/user.js
     create : ./views
     create : ./views/layout.jade
     create : ./views/index.jade 
  
     install dependencies:
       $ cd . &amp;&amp; npm install
  
     run the app:
       $ node app
  
  X:\server\--version&gt;
  </code></pre>
