//================
// Binaryen C API
//
// The first part of the API lets you create modules and their parts.
//
// The second part of the API lets you perform operations on modules.
//
// The third part of the API lets you provide a general control-flow
//   graph (CFG) as input.
//
// The final part of the API contains miscellaneous utilities like
//   debugging/tracing for the API itself.
//
// ---------------
//
// Thread safety: You can create Expressions in parallel, as they do not
//                refer to global state. BinaryenAddFunction and
//                BinaryenAddFunctionType are also thread-safe, which means
//                that you can create functions and their contents in multiple
//                threads. This is important since functions are where the
//                majority of the work is done.
//                Other methods - creating imports, exports, etc. - are
//                not currently thread-safe (as there is typically no need
//                to parallelize them).
