usage: wast2json [options] filename

  read a file in the wasm spec test format, check it for errors, and
  convert it to a JSON file and associated wasm binary files.

examples:
  # parse spec-test.wast, and write files to spec-test.json. Modules are
  # written to spec-test.0.wasm, spec-test.1.wasm, etc.
  $ wast2json spec-test.wast -o spec-test.json
