  "abstract": "It is argued that some phase--transitions observed in models of non-equilibrium wetting phenomena are related to contact processes with long-range interactions. This is investigated by introducing a model where the activation rate of a site at the edge of an inactive island of length $\\ell$ is $1+a\\ell^{-\\sigma}$. Mean--field analysis and numerical simulations indicate that for $\\sigma>1$ the transition is continuous and belongs to the universality class of directed percolation, while for $0<\\sigma<1$, the transition becomes first order. This criterion is then applied to discuss critical properties of various models of non--equilibrium wetting.",
