8# Config
9# ------

12#   repository.  By default they won't be.
13# hooks.allowdeletetag
14#   This boolean sets whether deleting tags will be allowed in the
15#   repository.  By default they won't be.
16# hooks.allowmodifytag
17#   This boolean sets whether a tag may be modified after creation. By default
18#   it won't be.
19# hooks.allowdeletebranch
20#   This boolean sets whether deleting branches will be allowed in the
21#   repository.  By default they won't be.
22# hooks.denycreatebranch
