/* ERROR/WARNING messages:

E: Group command before simulation box is defined

The group command cannot be used before a read_data, read_restart, or
create_box command.

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: Could not find group delete group ID

Self-explanatory.

E: Cannot delete group all

Self-explanatory.

E: Cannot delete group currently used by a fix

Self-explanatory.

E: Cannot delete group currently used by a compute

Self-explanatory.

E: Cannot delete group currently used by a dump

Self-explanatory.

E: Cannot delete group currently used by atom_modify first

Self-explanatory.

E: Too many groups

The maximum number of atom groups (including the "all" group) is
given by MAX_GROUP in group.cpp and is 32.

E: Group region ID does not exist

A region ID used in the group command does not exist.

E: Variable name for group does not exist

Self-explanatory.

E: Variable for group is invalid style

Only atom-style variables can be used.

E: Group ID does not exist

A group ID used in the group command does not exist.
