+    (description
+     "Agda is a dependently typed functional programming language: it has
+inductive families, which are similar to Haskell's GADTs, but they can be
+indexed by values and not just types.  It also has parameterised modules,
+mixfix operators, Unicode characters, and an interactive Emacs interface (the
+type checker can assist in the development of your code).  Agda is also a
+proof assistant: it is an interactive system for writing and checking proofs.
+Agda is based on intuitionistic type theory, a foundational system for
+constructive mathematics developed by the Swedish logician Per Martin-Löf.  It
+has many similarities with other proof assistants based on dependent types,
+such as Coq, Epigram and NuPRL.")
