Example of usage using command line interface
---------------------------------------------

Run this to generate a FORCE_CONSTANTS file and show a preview of the phonon band structure.
Use --dim to change the size of the supercells used to calculate the force constants.
use -c to generate a POSCAR type file containing the crystal unit cell to use in phonopy.
-p activates the phonon band structure preview,
--pa can be used to define the primitive axis in a same manner as phonopy (this option only
affects the phonon band structure preview):

# phonolammps in.lammps -c POSCAR_unitcell --dim 3 3 3 -p

or

# phonolammps in.lammps_data -c POSCAR_unitcell --dim 3 3 3 -p
