/* 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: Dihedral style hybrid cannot use same dihedral style twice

Self-explanatory.

E: Dihedral style hybrid cannot have hybrid as an argument

Self-explanatory.

E: Dihedral style hybrid cannot have none as an argument

Self-explanatory.

E: Dihedral coeff for hybrid has invalid style

Dihedral style hybrid uses another dihedral style as one of its
coefficients.  The dihedral style used in the dihedral_coeff command
or read from a restart file is not recognized.
