Awesome - thanks for the pointer. That makes so much more sense and
explains how fence_tool can introspect the options passed to the
particular fencer.
I've attached an updated version that follows the specifications at

it, though I haven't done any substantial testing yet.
Thanks for the help - feel free to use/distribute/forget about it :)

make empty prophecies. The danger already exists that the mathematicians
have made a covenant with the devil to darken the spirit and to confine
man in the bonds of Hell."
