A short history of phonopy

Phonopy development started to replace and extend fropho ( The implementation of fropho is also based on Parlinski-Li-Kawazoe method. Although fropho was implemented from scratch except for the symmetry finder and input file parser, to start the development, it was motivated by the existence of PHON code. The important part of the implementation is the symmetry handling. In fropho, at first the symmetry finder in Abinit code was employed, but later the symmetry finder was replaced by spglib (
