+# An example hook script to blocks unannotated tags from entering.
+# Called by git-receive-pack with arguments: refname sha1-old sha1-new

+# To enable this hook, make this file executable by "chmod +x update".

+# ------
+# 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.allowdeletebranch
+#   This boolean sets whether deleting branches will be allowed in the
+#   repository.  By default they won't be.
