1. Click on the 'Raw' button. Download and save the file to your Desktop.
2. Open Terminal.app
3. In terminal prompt, make the file executable by running the following command (copy paste the command and hit return key)
   chmod +x ~/makeapp.sh
4. Execute the script
   ~/makeapp.sh

Great script! But how do I prevent links to open in that new app instead of the standard chrome profile? If all links I open in my new Gmail app open there instead of my browser that kind of defeats the purpose of such an app. Any ideas? Can I force links to open in my standard Chrome profile?
