+[Copybara][copybara] configuration used to sync the private repo with the
+public one, excluding personal files I do not want to share with the world :)
+
+## How to test the Copybara script
+
+1. Clone the private and public repos in your computer.
+2. Create a `test_repos_config.sky` file with the following contents:
+  ```sky
+test_origin_url = "file:///path/to/private/dotfiles"
+test_destination_url = "file:///path/to/dotfiles-external"
+```
+3. Run `sh export-commits-test.sh`.
