-C, --call-stack-size=SIZE
Size in elements of the call stack
-t, --trace
Trace execution
Run all the exported functions, in order. Useful for testing
Include an importable function named "host.print" for printing to stdout


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
