Python script example fails to execute, since about.txt is not executable

[oskirby]

The python script contains an about.txt that was probably meant to be informative rather than an actual script that can execute on the camera, but attempting to run it results in an error due to the file not being executable.

This script should be written (and packaged) in such a way that the user can execute it, and see the script in action.
