| # - Github Version Control Checker | |
| # - Watches changes on version-controlled contracts and makes sure that versions are bumped in case of relevant changes: | |
| # - Relevant changes == anything except for changes of license identifier, solidity pragma of pure comment changes | |
| # - watched paths: src/* | |
| # - will check all modified or new contracts in watched paths | |
| # - will fail if a new contract was added to watched paths without contract version | |
| # - will fail if an existing contract was modified but version was not updated | |
| # - will update the PR title to contain all contract names and their new versions (watched paths only) | |
