-# An example hook script to mail out commit update information.
-# It can also blocks tags that aren't annotated.
+# 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".
#
# Config
# ------
-# hooks.mailinglist
-# This is the list that all pushes will go to; leave it blank to not send
-# emails frequently. The log email will list every log entry in full between
-# the old ref value and the new ref value.
-# hooks.announcelist
-# This is the list that all pushes of annotated tags will go to. Leave it
-# blank to just use the mailinglist field. The announce emails list the
-# short log summary of the changes since the last annotated tag
# hooks.allowunannotated
# This boolean sets whether unannotated tags will be allowed into the
# repository. By default they won't be.
#
-# Notes
-# -----
-# All emails have their subjects prefixed with "[SCM]" to aid filtering.
-# All emails include the headers "X-Git-Refname", "X-Git-Oldrev",
-# "X-Git-Newrev", and "X-Git-Reftype" to enable fine tuned filtering and info.
