If you haven’t gotten these two softwares on hand as mentioned before, you can download Python on its official website, and download Google App Engine SDK for Python from Google Code.

After that, install both of them.

After downloads, extract the zip files.

Step 4. To edit the app.yaml file

freenuts gae gappproxy

Open the “app.yaml” file in the fetchserver folder, and change the application name “your_application_name” to your new GAE application ID, such as “freenutsdotorg”, then save the file.
