[Pw_forum] pseudopotential conversion

[Silviu Zilberman]

I tested the converter some time ago, and there are slight 
disagreements. I generated a NCPP (with the 'atom' code), and used it as 
input once in the original pw format, and once after converting to UPF. 
The differences in the energy are not huge, of the order of third/fourth 
decimal digit. It seems like a roundoff error of the converter. In most 
cases these would be minor differences, however for me it made a difference.
