Hello Cyrus!

Let's start with the first program:

import std::io;

fn main() {
    io::printfn("Hello, Cyrus\n");
}

Compiling the program

Let's take the above program and put it in a file called hello_world.cyrus.

We can then run it with:

cyrus run hello_world.cyrus

It should print Hello, World! and return back to the command line prompt.
