[Pw_forum] CVS Changes in output file format

[Paul M. Grant]

Paolo, just don't change the description/location of the Fermi energy!

I'm rather curious about your remark that dforceb.f may still contain
errors...isn't this a key routine in Berry phase calculations?

what was it for this one?

the reason was to make the output more informative (or at least
less obscure) and more consistent. I and you know what all those
variables mean, but for most people those number mean close to
nothing. "nbnd" and "nelec" are listed respectively as "number of
electrons" and "number of Kohn-Sham states".

About "dforceb" and gfortran, I think this is the relevant change:
