d@0: #   repository.  By default they won't be.

d@0: #   This boolean sets whether deleting tags will be allowed in the
d@0: #   repository.  By default they won't be.
d@0: # hooks.allowmodifytag
d@0: #   This boolean sets whether a tag may be modified after creation. By default
d@0: #   it won't be.
d@0: # hooks.allowdeletebranch
d@0: #   This boolean sets whether deleting branches will be allowed in the
d@0: #   repository.  By default they won't be.
d@0: # hooks.denycreatebranch
d@0: #   This boolean sets whether remotely creating branches will be denied
d@0: #   in the repository.  By default this is allowed.
