Chris@14: # hooks.allowdeletetag
Chris@14: #   This boolean sets whether deleting tags will be allowed in the
Chris@14: #   repository.  By default they won't be.
Chris@14: # hooks.allowmodifytag
Chris@14: #   This boolean sets whether a tag may be modified after creation. By default
Chris@14: #   it won't be.
Chris@14: # hooks.allowdeletebranch
Chris@14: #   This boolean sets whether deleting branches will be allowed in the
Chris@14: #   repository.  By default they won't be.
Chris@14: # hooks.denycreatebranch
Chris@14: #   This boolean sets whether remotely creating branches will be denied
Chris@14: #   in the repository.  By default this is allowed.
