How to use modules in Opa?

Question

OK, this is pretty basic question, but I cannot figure this out... What is the correct way to call functions from modules? The way I do it is:

main.opa:

function start(){
    Page.page();
}

Server.start(
    Server.http, 
    [
        {title: "Calculator", page: start}
    ]
);

Where in the other, page.opa file I have:

module Page {
    function page(){
         <p>Consider this as html block...</p>
    }
}

Now, the error I get is that Page variable is unbound (it's not a variable at all!). Both files are in the same location.

How you compile your application? The following command should well works

opa page.opa main.opa

Then run the produced JavaScript file as an executable

./main.js

Or use the "--" option of the Opa compiler to compile and run

opa page.opa main.opa --
