These can be activated using the -DLAMMPS_EXCEPTIONS compiler flag. It has no effect for regular execution. However, while using it as a library, any issued command will capture the exception and save its error message. This can be queried using the lammps_has_error() and lammps_get_last_error_message() methods. The Python wrapper checks these in order to rethrow these errors as Python exceptions. See issue #146.
