+# This program is based on the post-receive-email hook script in the

+#
+# The post-receive-mail hook script is Copyright (c) 2007 Andy Parkins
+#
+# Config
+# ------
+# hooks.mailinglist
+#   This is the list that all pushes will go to; leave it blank to not send
+#   emails for every ref update.
+# hooks.envelopesender
+#   If set then the -f option is passed to sendmail to allow the envelope
+#   sender address to be set
+# hooks.emailprefix
+#
+#   All emails have their subjects prefixed with this prefix, or
+#   "[Mailing List Prefix]" if emailprefix is unset, to aid filtering
+#
+# Notes
+# -----
+# All emails include the headers "X-Git-Refname", "X-Git-Oldrev",
+# "X-Git-Newrev", and "X-Git-Reftype" to enable fine tuned filtering and
+# give information for debugging.
+#

+# should even be generated.
