+<h3>Pure</h3>
+
+<p>Pure (http://pure-lang.googlecode.com/) is an algebraic/functional
+programming language based on term rewriting. Programs are collections of
+equations which are used to evaluate expressions in a symbolic fashion. The
+interpreter uses LLVM as a backend to JIT-compile Pure programs to fast native
+code. Pure offers dynamic typing, eager and lazy evaluation, lexical closures, a
+hygienic macro system (also based on term rewriting), built-in list and matrix
+support (including list and matrix comprehensions) and an easy-to-use interface
+to C and other programming languages (including the ability to load LLVM bitcode
+modules, and inline C, C++, Fortran and Faust code in Pure programs if the
+corresponding LLVM-enabled compilers are installed).</p>
+
+<p>Pure version 0.54 has been tested and is known to work with LLVM 3.1 (and
+continues to work with older LLVM releases >= 2.5).</p>
