| ########################### | |
| # | |
| # This runs the calibre GitHub action to compress our images | |
| # | |
| # This Action has a few different methoids for running: | |
| # 1) For Pull Requests from and to the main repo it can run and update the PR | |
| # 2) For pushes to main, it will run and create a new PR. This captures PR from | |
| # Forks. | |
| # 3) It also runs every sunday at 11pm in case anything else sneaks in or any | |
| # improvements are added to Calibre. This will also open a PR if necessary. | |
| # 4) Finally it can be kicked off manually and it will open a PR if necessary. | |
