- \n\
- Use the 'plist attribute instead of the C API 'user attribute\n\

- \n\
- As you can see, argument numbers are zero based. The type of each argument\n\

- define any semantics for the string value of 'arg_type. Conventionally\n\
- \"string\" is used for strings and \"int\" for 32 bit integers. Note that\n\
