emscripten 1.22.1-1build1 (i386 binary) in ubuntu wily

 Emscripten is an LLVM to JavaScript compiler. It takes LLVM bitcode, also
 called LLVM IR (which can be generated from C/C++ using Clang, or any other
 language that can be converted into LLVM bitcode) and compiles that into
 JavaScript, which can be run on the web (or anywhere else JavaScript can run).
 .
 Using Emscripten, you can
   * Compile C and C++ code into JavaScript and run that on the web
   * Run code in languages like Python as well, by compiling CPython from C
     to JavaScript and interpreting code in that on the web
