+receive.procReceiveRefs::
+	This is a multi-valued variable that defines reference prefixes
+	to match the commands in `receive-pack`.  Commands matching the
+	prefixes will be executed by an external hook "proc-receive",
+	instead of the internal `execute_commands` function.  If this
+	variable is not defined, the "proc-receive" hook will never be
+	used, and all commands will be executed by the internal
+	`execute_commands` function.
++
+For example, if this variable is set to "refs/for", pushing to reference
+such as "refs/for/master" will not create or update a reference named
+"refs/for/master", but may create or update a pull request directly by
+running the hook "proc-receive".
++
+Optional modifiers can be provided in the beginning of the value to filter
+commands for specific actions: create (a), modify (m), delete (d).
+A `!` can be included in the modifiers to negate the reference prefix entry.
+E.g.:

+	git config --system --add receive.procReceiveRefs ad:refs/heads
+	git config --system --add receive.procReceiveRefs !:refs/heads

+~~~~~~~~~~~~
+
+This hook is invoked by linkgit:git-receive-pack[1].  If the server has
+set the multi-valued config variable `receive.procReceiveRefs`, and the
+commands sent to 'receive-pack' have matching reference names, these
+commands will be executed by this hook, instead of by the internal
+`execute_commands()` function.  This hook is responsible for updating
+the relevant references and reporting the results back to 'receive-pack'.
+
+This hook executes once for the receive operation.  It takes no
+arguments, but uses a pkt-line format protocol to communicate with
+'receive-pack' to read commands, push-options and send results.  In the
+following example for the protocol, the letter 'S' stands for
+'receive-pack' and the letter 'H' stands for this hook.
+
+    # Version and features negotiation.
+    S: PKT-LINE(version=1\0push-options atomic...)
+    S: flush-pkt
+    H: PKT-LINE(version=1\0push-options...)
+    H: flush-pkt
+
+    # Send commands from server to the hook.
+    S: PKT-LINE(<old-oid> <new-oid> <ref>)
+    S: ... ...
+    S: flush-pkt
+    # Send push-options only if the 'push-options' feature is enabled.
+    S: PKT-LINE(push-option)
+    S: ... ...
+    S: flush-pkt
+
+    # Receive result from the hook.
+    # OK, run this command successfully.
+    H: PKT-LINE(ok <ref>)
+    # NO, I reject it.
+    H: PKT-LINE(ng <ref> <reason>)
+    # Fall through, let 'receive-pack' to execute it.
+    H: PKT-LINE(ok <ref>)
+    H: PKT-LINE(option fall-through)
+    # OK, but has an alternate reference.  The alternate reference name
+    # and other status can be given in option directives.
+    H: PKT-LINE(ok <ref>)
+    H: PKT-LINE(option refname <refname>)
+    H: PKT-LINE(option old-oid <old-oid>)
+    H: PKT-LINE(option new-oid <new-oid>)
+    H: PKT-LINE(option forced-update)
+    H: ... ...
+    H: flush-pkt
+
+Each command for the 'proc-receive' hook may point to a pseudo-reference
+and always has a zero-old as its old-oid, while the 'proc-receive' hook
+may update an alternate reference and the alternate reference may exist
+already with a non-zero old-oid.  For this case, this hook will use
+"option" directives to report extended attributes for the reference given
+by the leading "ok" directive.
+
+The report of the commands of this hook should have the same order as
+the input.  The exit status of the 'proc-receive' hook only determines
+the success or failure of the group of commands sent to it, unless
+atomic push is in use.
