Here an example, save it as example.d:

```d
#!/usr/bin/env dub

/+ dub.json:
{
     "name":"example-s3",
     "dependencies":{
         "aws-sdk:core": "1.0.0",
         "aws-sdk:s3": "1.0.0"
     }
}
+/

import aws.sdk.core, aws.sdk.s3;

void main()
{
     auto client = new AwsClient();
     auto s3 = new S3Service(client);

     ...
}
```

On linux you could start this file using command 
```./example.d```.
Or with command ```dub example.d```.

Kind regards
