 To provide those capabilities, Binaryen has a simple and flexible API for **representing and processing** WebAssembly modules. The interpreter, validator, pretty-printer, etc. are built on that foundation. The core of this is in [wasm.h](https://github.com/WebAssembly/binaryen/blob/master/src/wasm.h), which contains classes that define a WebAssembly module, and tools to process those. For a simple example of how to use Binaryen, see [test/example/find_div0s.cpp](https://github.com/WebAssembly/binaryen/blob/master/test/example/find_div0s.cpp), which creates a module and then searches it for a specific pattern.

 * `binaryen-shell` and `asm2wasm` require a C++11 compiler.
 * If you also want to compile C/C++ to WebAssembly (and not just asm.js to WebAssembly), you'll need Emscripten. You'll need the `incoming` branch there (which you can get via [the SDK](http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html)).
