/* 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: Angle style hybrid cannot use same angle style twice

Self-explanatory.

E: Angle style hybrid cannot have hybrid as an argument

Self-explanatory.

E: Angle style hybrid cannot have none as an argument

Self-explanatory.

E: BondAngle coeff for hybrid angle has invalid format

No "ba" field should appear in data file entry.

E: BondBond coeff for hybrid angle has invalid format

No "bb" field should appear in data file entry.

E: Angle coeff for hybrid has invalid style

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

E: Invoked angle equil angle on angle style none

Self-explanatory.

E: Invoked angle single on angle style none

Self-explanatory.
