Script to open and render blend files in sequence

Is it possible and how do you write a script (for use inside or outside Blender) that will open a blend file, render an animation, open another blend file, render another animation, and so on? I have a number of blend files ready to animate. It will take days to complete the sequence. I would like to just set up a batch and let the computer churn without watching it. Thanks.

Have you looked at Blender’s command line options? Try ‘blender -h’
