   2#
   3# An example hook script to blocks unannotated tags from entering.
   4# Called by git-receive-pack with arguments: refname sha1-old sha1-new
   5#
   6# To enable this hook, rename this file to "update".
   7#
   8# Config
   9# ------
  10# hooks.allowunannotated
  11#   This boolean sets whether unannotated tags will be allowed into the
  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
  23#   This boolean sets whether remotely creating branches will be denied
  24#   in the repository.  By default this is allowed.
