     "Dependently typed functional programming language and proof assistant")
    (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.")

     "The goal is to provide a concrete library focused on verification
examples, as opposed to mathematics.  The library has a good number
of theorems for booleans, natural numbers, and lists.  It also has
trees, tries, vectors, and rudimentary IO.  A number of good ideas
come from Agda's standard library.")
