User:Owittnan/A little Rust primer/Hello Rust!

Below is the standard Rust "Hello, world!" program.

It's pretty easy to see what it does.

`fn main` defines a function called main. This is the entry point into your Rust program.

`println!" prints a string and appends a newline.

So running this code will print "Hello, world!" to standard output. Cool. Let's do something more advanced.
