%global lammps_desc \
LAMMPS is a classical molecular dynamics code, and an acronym for Large-scale \
Atomic/Molecular Massively Parallel Simulator.\
\
LAMMPS has potentials for soft materials (biomolecules, polymers) and \
solid-state materials (metals, semiconductors) and coarse-grained or \
mesoscopic systems. It can be used to model atoms or, more generically, as a \
parallel particle simulator at the atomic, meso, or continuum scale. \
\
LAMMPS runs on single processors or in parallel using message-passing \
techniques and a spatial-decomposition of the simulation domain. The code is \
designed to be easy to modify or extend with new functionality.
