This information is all in the remlog file. I removed it from the mdout
files because it was redundant, and if the exchange frequency is high
(which yields better convergence), then the mdout file gets very large
but does not contain particularly useful information, in my opinion.

If for whatever reason you want this output printed to the mdout like in
Amber 10, you can recompile Amber 12 like this:

./configure -mpi <compiler>
