/* ERROR/WARNING messages:
E: Illegal ... command
Self-explanatory.  Check the input script syntax and compare to the
documentation for the command.  You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.
E: Incorrect args for pair coefficients
Self-explanatory.  Check the input script or data file.
E: Pair cutoff < Respa interior cutoff
One or more pairwise cutoffs are too short to use with the specified
rRESPA cutoffs.
