usage: wasm-interp [options] filename [arg]...

  read a file in the wasm binary format, and run in it a stack-based
  interpreter.

examples:
  # parse binary file test.wasm, and type-check it
  $ wasm-interp test.wasm

  # parse test.wasm and run all its exported functions
  $ wasm-interp test.wasm --run-all-exports

  # parse test.wasm, run the exported functions and trace the output
  $ wasm-interp test.wasm --run-all-exports --trace

  # parse test.wasm and run all its exported functions, setting the
  # value stack size to 100 elements
  $ wasm-interp test.wasm -V 100 --run-all-exports

  # parse test.wasm, run specific exported function by name with argument
  $ wasm-interp test.wasm -r "func_sum" -a "i32:8" -a "i32:5"
