Gabor Pali bfe69bdfaa 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-Lof. It has many similarities with other proof assistants based on
dependent types, such as Coq, Epigram and NuPRL.

Note that if you want to use the command-line program (agda), then
you should also install the Agda-executable package. The Agda
package includes an Emacs mode for Agda, but you need to set up the
Emacs mode yourself (for instance by running agda-mode setup; see
the README).
Note also that this library does not follow the package versioning
policy, because the library is only intended to be used by the Emacs
mode and the Agda-executable package.
