there is nothing to comment. The phonon code is very complex
(36000 specific lines, plus many thousands more from PW and
from libraries). I would say it is the most complex in the QE
distribution. Without a clear idea of how the theory works, or
even WITH a clear idea, it is hard to understand how the code
works. The only way is to delve into the code and figure out
what the different pieces do; then, locate the piece that performs
the operations you are interested in.
