description             functional programming language based on term rewriting

long_description        Pure is a functional programming language based on \
                        term rewriting. It has a modern syntax featuring \
                        curried function applications, lexical closures and \
                        equational definitions with pattern matching, and \
                        thus is somewhat similar to languages of the Haskell \
                        and ML variety. But Pure is also a very dynamic and \
                        reflective language, and is more like Lisp in this \
                        respect. The interpreter has an LLVM backend to do \
                        JIT compilation, hence programs run blazingly fast \
                        and interfacing to C modules is easy. The libraries \
                        are licensed under LGPL-3, the interpreter is GPL-3, \
                        and the examples are BSD-licensed.
