     --no-canonicalize-leb128s
             Write all LEB128 sizes as 5-bytes instead of their minimal size

     --debug-names
             Write debug names to the generated binary file

     --no-check
             Don't check for invalid modules

EXAMPLES

     Parse test.wat and write to .wasm binary file with the same name

           $ 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
