 The documentation online would look like `spawn(move || { fib(200); })`, but when

+Rustdoc will automatically add a `main()` wrapper around your code, and in the right
+place. For example:
+
+```
+/// ```
+/// use std::rc::Rc;
+///
+/// let five = Rc::new(5);

+
+Here's the full algorithm:
+
+1. Given a code block, if it does not contain `fn main`, it is wrapped in `fn main() { your_code }`
+2. Given that result, if it contains no `extern crate` directives but it also
+   contains the name of the crate being tested, then `extern crate <name>` is
