+description = """Octopus is a scientific program aimed at the ab initio
+virtual experimentation on a hopefully ever-increasing range of system
+types. Electrons are described quantum-mechanically within
+density-functional theory (DFT), in its time-dependent form (TDDFT) when
+doing simulations in time. Nuclei are described classically as point
+particles. Electron-nucleus interaction is described within the
+pseudopotential approximation."""
