The Nuclear Network Generator (Netgen) is a tool to generate nuclear-reacti
on rates for networks and temperature grids specified by the user. Nuclear-
reaction net-works relevant to a large variety of astrophysical situations
may be generated, including big-bang nucleosynthesis, stellar hydrogen-, he
lium- and later burning phases (hydrostatic and explosive), synthesis of he
avy nuclei (s-, r-, p-, rp-, alpha -processes). Netgen is available at the
