// A minimal "hello world" style example of how to use Sandboxed API. This
// example does not include any error handling and will simply abort if
// something goes wrong.
// As the library function that is being called into is pure computation (i.e.
// does not issue any syscalls), the restricted default sandbox policy is being
// used.
