+.SH DESCRIPTION
+.B LAMMPS 
+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.
