Use what='scf_ph'. See example16 and example20.
Please note that this calculation is made by the extended version of the
phonon code available in thermo_pw, so you have to provide specific flags
to the phonon input. See the user's guide for details.
The dielectric constant is in the file output_epsilon.ps.
Note that for metals you need to specify a finite wave-vector q and you
cannot plot the dielectric constant when q is the 
point.
See example17 and example21 for this case.
