dnl Too many people are not aware of maintainer mode:
dnl If you want to use it, you definitely know what you are doing, so
dnl you can specify "--disable-maintainer-mode". But if you want the default
dnl automake behavior, you've likely never heard of maintainer mode, so we
dnl can't expect you to enable it manually.
