Hi David,

This feature (B.10) does not give more efficient/accurate calculations
of the static dielectric properties. It allows the calculation of
electric-field-dependence of Born effective charges and dielectric 
tensor. You can read this paper, Phys. Rev. B 75, 115116 (2007),
for details.

Regards,
Xinjie
