What's the easiest way for a shell script to tell if grub version 1 is installed?

[Stephen Powell <zlinuxman@wowway.com>]

What's the easiest way for a shell script to tell if grub version 1
is installed?  It is important to distinguish grub version 1 from
grub version 2.  For example, can I just do this?

if [ -f /boot/grub/menu.lst ];then
   blah
   blah
   blah
fi

Or does that file exist in grub version 2 as well?  I don't have
grub version 2 installed on any of my machines; so I can't easily
determine this.
