    <<-EOS.undent
    You must manually edit #{apache_configdir}/httpd.conf to include
      LoadModule bonjour_module #{libexec}/mod_bonjour.so

    Add the following to your virtual host conf files to advertise them on bonjour. The
    last number is whatever port the virtual host is listening on.

        <IfModule bonjour_module>
            RegisterResource "Site Title" / 80
        </IfModule>

    NOTE: If you're _NOT_ using --with-brewed-httpd22 or --with-brewed-httpd24 and having
    installation problems relating to a missing `cc` compiler and `OSX#{MACOS_VERSION}.xctoolchain`,
    read the "Troubleshooting" section of https://github.com/Homebrew/homebrew-apache
