ATS version 2 programming language compiler

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. In addition, ATS contains a component ATS/LF that supports a form of (interactive) theorem proving, where proofs are constructed as total functions. With this component, ATS advocates a programming style that combines programming with theorem proving. Furthermore, this component may be used as a logical framework to encode various deduction systems and their (meta-)properties. This package contains the compiler patsopt and the frontend patscc, as well as the emacs mode for the language.
