Comment # 2 on bug 933004 from Roman Bysh

There are two ways to incorporate the browser GOOGLE_API_KEY.

1. Assign your API key at build time of minitube (preferable)
2. The user can also create their own personal browser GOOGLE_API_KEY and add  
it to their environmental variables.

How to create the environmental variables for minitube operation.

Create a file /etc/profile.d/minitube.sh 

Add the line below:

export APP_GOOGLE_API_KEY="your-google-data-api-key"


Start minitube 2.4x and the user will have access to the Google servers and
play
Youtube videos.
