			Phonon dispersion post-processing tool

			This program reads the binary file created by fix_phonon and helps to
			analyse the phonon related info.

			The clapack library is needed to solve the eigen problems,
			which could be downloaded from:
			http://www.netlib.org/clapack/

			The tricubic library is also needed to to tricubic interpolations,
			which could be obtained from:
			http://orca.princeton.edu/francois/software/tricubic/

			The spglib (version 0.7.1) is optionally needed, enabling one to
			evaluate the phonon density of states or vibrational thermal
			properties using only the irreducible q-points in the first
			Brillouin zone.

			To compile the code, one needs therefore to install the above
			libraries and set the paths correctly in the Makefile.

			The units of the output frequencies by this code is THz for LAMMPS
			units "real", "si", "metal", and "cgs"; in these cases, the
			frequencies are $\nu$ instead of $\omega$.
