Thank you, Nicola: this is good news! May I suggest that not the
person(s) who will "soon" make the job on CP
try to make a special effort to make the work easily portable to the
two other codes of the
the O-sesame suit (PWscf/CP/FPMD, ideally, "trivially portable", i.e.
a same module
to be used for the three codes). This may require more work at this
stage, but I believe this
is the right policy to save work in the long run.
