 This package provides Julia bindings for the [extxyz](https://github.com/libAtoms/extxyz) C library which implements a parser and writer for the extended XYZ file format used in materials and molecular modelling, following the [specification](https://github.com/libAtoms/extxyz#extended-xyz-specification-and-parsing-tools) set out in the extxyz repo. Moreover the `ExtXYZ.Atoms` object directly adheres to the [AtomsBase](https://github.com/JuliaMolSim/AtomsBase.jl) common interface for atomistic structures.
