Hi,

It's often nice as a user to know that the program has agreed with your
intentions :-) You're using a tabulated interaction, so AFAICR mdrun just
does what you say. In some cases, mdrun will generate tables to implement
the user's short-ranged options, and it's important that mdrun says what
it's doing, and helpful if it always does so in similar ways.
