| # An example hook script to block unannotated tags from entering. |
| # Called by "git receive-pack" with arguments: refname sha1-old sha1-new |
| # |
| # To enable this hook, rename this file to "update". |
| # |
| # Config |
| # ------ |
| # hooks.allowunannotated |
| # This boolean sets whether unannotated tags will be allowed into the |
| # repository. By default they won't be. |
| # hooks.allowdeletetag |
| # This boolean sets whether deleting tags will be allowed in the |
| # repository. By default they won't be. |
| # hooks.allowmodifytag |
| # This boolean sets whether a tag may be modified after creation. By default |
| # it won't be. |
| # hooks.allowdeletebranch |
| # This boolean sets whether deleting branches will be allowed in the |
| # repository. By default they won't be. |
| # hooks.denycreatebranch |
| # This boolean sets whether remotely creating branches will be denied |
| # in the repository. By default this is allowed. |
