That's really up to you, but here are some examples:
* **config files**: some programs auto-write their config files, without waiting for you to click an 'Apply' button; or even if there is such a button, most programs offer you no way of going back to an earlier version of your settings. If you commit your config file(s) to a git repo, you can track changes and go back to older versions. This script makes it convenient, to have all changes recorded automatically.
* *more stuff!* If you have any other uses, or can think of ones, please let us know, and we can add them to this list!
