+Usage: ${PN} [-f] [-c] [-q] [-l [-L]] [-C] [-- make-flags]
 Update the generated files in the Emacs autogen/ directory.
 Options:
 -f: force an update even if the source files are locally modified.
@@ -60,6 +60,7 @@ Options:
 -q: be quiet; only give error messages, not status messages.
 -l: also update the versioned loaddefs-like files in lisp/.
 This requires a build.  Passes any non-option args to make (eg -- -j2).
+-L: also update ldefs-boot.el.
 -C: start from a clean state.  Slower, but more correct.
