Hosting an existing site on google app engine

I have been getting used to using the google app engine and all of its awesomeness. I searched online for taking an existing site and using the google app engine to host it. I saw this post How to Host your Website on Google for Free but I like my files separated into folders (images, style, newsletters, etc) and not have all of the files in the same directory. So with a little modification to app.yaml I can have my site organized. I plan to use the app engine to host this website I made once my godaddy hosting expires I will switch over. This is my website on appspot.

If you want the project files you can get them here.
Below is the app.yaml.
