usage: wat2wasm [options] filename

  read a file in the wasm text format, check it for errors, and
  convert it to the wasm binary format.

examples:
  # parse and typecheck test.wat
  $ wat2wasm test.wat

  # parse test.wat and write to binary file test.wasm
  $ wat2wasm test.wat -o test.wasm

  # parse spec-test.wast, and write verbose output to stdout (including
  # the meaning of every byte)
  $ wat2wasm spec-test.wast -v
