| # Instructions | |
| # | |
| # - One-time setup: create a personal access token with permissions. Then configure it here | |
| # as secrets.CI_PAT. https://github.com/boostorg/boost/settings/secrets/actions | |
| # The reason is explained in https://github.com/orgs/community/discussions/25702 | |
| # "If an action pushes code using the repository's GITHUB_TOKEN, a new workflow will not run" | |
| # | |
| # - Processing of either the 'master' or 'develop' branch may be stopped by creating the variables | |
| # vars.block_master or vars.block_develop with any value. | |
| # https://github.com/boostorg/boost/settings/variables/actions | |
| # | |
| # To avoid infinite loops, don't trigger on "push" | |
