This directory contains the necessary parts for building a library with FFI
access to the Wasm spec interpreter. Its major parts:
 - `spec`: the Wasm spec code as a Git submodule (you may need to retrieve it:
   `git clone -b wasmtime_fuzzing https://github.com/conrad-watt/spec`).
 - `interpret.ml`: a shim layer for calling the Wasm spec code and exposing it
   for FFI access
 - `Makefile`: the steps for gluing these pieces together into a static library

Note: the `Makefile` must be configured with the path to `libgmp.a`; see
`LIBGMP_PATHS` in the `Makefile` (Ubuntu: `libgmp-dev`, Fedora: `gmp-static`).
