It will go off by itself, but only if you turn on the AI for your side
(either in the player setup dialog or later in the Side menu). Moreover "AI
control" has to be checked for the unit. AI control is on by default, so
when you turn on the AI it will seize control of all units for which you
did not disable AI control.

Once the AI takes over a unit, it will scrap any previous plan and pick its
own. It may happen that the AI also thinks it is a good idea to explore, in
which case the unit may keep an exploratory plan. But this is pure
coincidence. What the plan type was set to before the AI took over does not
matter.

This is the relevant code from set_side_ai:

if (gameinited) {
    /* Replan everything, whether switching to ai or human control. */
    DMprintf("%s is replanning all units after ai switch.\n",
side_desig(side));
    for_all_side_units(side, unit) {
        if (is_active(unit)) {
            /* We do this locally on each computer to save time. */
            unit->aihook = NULL;
            force_replan(unit);
        }
    }
}

To avoid confusion I have disabled the plan type menu in the CVS sources. I
will put it back if/when I implement the semi-automatic mode for AI control.
