ATS2 a.k.a. ATS/Postiats is a programming language with a highly expressive type system rooted in the framework Applied Type System. In particular, both dependent types and linear types are available in ATS. The current implementation of ATS (ATS/Postiats) is written in ATS (ATS/Anairiats) itself. It can be as efficient as C/C++ and supports a variety of programming paradigms.

This package contains the emacs mode for ATS2.
