+      Alloy is a language for describing structures and a tool for exploring
+      them. An Alloy model is a collection of constraints that describes a set
+      of structures, e.g. all the possible security configurations of a web
+      application, or all the possible topologies of a switching network. The
+      Alloy Analyzer is a solver that takes the constraints of a model and
+      finds structures that satisfy them. Structures are displayed graphically,
+      and their appearance can be customized for the domain at hand.
