		Agda is a dependently typed functional programming language: It has
		inductive families, which are similar to Haskell&#39;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-L&amp;#xf6;f. It has many
		similarities with other proof assistants based on dependent types,
		such as Coq, Epigram and NuPRL.
		
		This package includes both a command-line program (agda) and an
		Emacs mode. If you want to use the Emacs mode you can set it up by
		running @agda-mode setup@ (see the README).
		
		Note that the Agda package does not follow the package versioning
		policy, because it is not intended to be used by third-party
		packages.
