Follow OpenBabel3/OpenBabel-js/readme.txt and the included make/Makefile to
build with Emscripten. The Open Babel 3.1.1 release retains the internal
version string 3.1.0. The shipped WASM and data files match the binding
revision above byte for byte. This website obtains them from the pinned
kekule@1.0.3 package. It does not modify the WASM or chemistry data.

The JavaScript module adapter adds only:
  export default OpenBabelModule;

The original loader, module adapter and binaries are available together
under ../runtime/openbabel/. The adapter-generation script and browser
worker source are available in the website source repository:
