+=item getBMCTarget(C<TargetsObj>)
+
+Returns the target string for the BMC chip.  If it can't find one,
+it will die.  Currently supports single BMC systems.
+
+=item getChildUnitsWithTargetType(C<TargetsObj>, C<TargetType>, C<ChipTarget>)
+
+Returns an array of targets that have target-type C<TargetType>
+and are children (any level) of target C<ChipTarget>.
