How to compile the example given in the book correctly? When 
compiling, an error occurs that the main function is missing. If 
I replace `shared static this()` with `void main()', then 
everything starts. What does the compilation string in `dub` and 
`dmd` look like correctly?

```d
import vibe.d;

shared static this()
{
   auto settings = new HTTPServerSettings;
   settings.port = 8080;
   settings.bindAddresses = ["::1", "127.0.0.1"];
   listenHTTP(settings, &hello);

   logInfo("Please open http://127.0.0.1:8080/ in your browser.");
}

void hello(HTTPServerRequest req, HTTPServerResponse res)
{
   res.writeBody("Hello, World!");
}
```

 ```

This seems to work for me:

```d
/+ dub.json: {
     "name": "test",
     "dependencies": {
         "vibe-d": "*"
     }
} +/
import vibe.d;

shared static this()
{
   auto settings = new HTTPServerSettings;
   settings.port = 8080;
   settings.bindAddresses = ["::1", "127.0.0.1"];
   listenHTTP(settings, &hello);

   logInfo("Please open http://127.0.0.1:8080/ in your browser.");
}

void main() {
     runApplication;
}

void hello(HTTPServerRequest req, HTTPServerResponse res)
{
   res.writeBody("Hello, World!");
}
```

Run with

```
dub run --single test.d
```

Originally vibe.d included its own main function by default. That is now 
opt-in instead of opt-out. Circa 2016.

You can either add the version ``VibeDefaultMain`` or use a main 
function and call ``runApplication`` yourself.
