+     "This package provides tools for the statistical modelling of spatial
+extremes using max-stable processes, copula or Bayesian hierarchical models.
+More precisely, this package allows (conditional) simulations from various
+parametric max-stable models, analysis of the extremal spatial dependence, the
+fitting of such processes using composite likelihoods or least square (simple
+max-stable processes only), model checking and selection and prediction.")
