`hooks.allowunannotated` config option unset or set to false--prevents
unannotated tags to be pushed.
+[[proc-receive]]
+proc-receive
+~~~~~~~~~~~~
+This hook is invoked by linkgit:git-receive-pack[1] when it reacts to
+special `git push` command. According to refnames of the commands which
+`git push` sends to 'git-receive-pack', the commands will be devided
+into two groups by matching what the `receive.procReceiveRefs`
+configuration variable defines. One group of the commands will execute
+the internal `execute_commands` function to update the corresponding
+refnames, and the other group of commands which have matching refnames
+will execute this 'proc-receive' hook to create pull requests, etc.
+If there is no `receive.procReceiveRefs` settings, this hook won't
+execute at all, and all commands are sent to the internal
+`execute_commands` function.
+
+Its exit status only determines the success or failure of the group of
+commands with special refnames, unless atomic push is in use.
+
+This hook executes once for the receive operation. It takes no
+arguments, but gets the same information as the
+<<pre-receive,'pre-receive'>> hook does on its standard input.
