The script can probably be generalized to take a file name as argument. For GitHub we'd then pass `$GITHUB_STEP_SUMMARY`, whereas for GitLab we pass in a temporary filename that we than simply cat(1) to the console. That'd allow us to move the CI-specific bits into the respective CIs whereas the script itself remains generic. Patrick
