I just place `main` in a separate skeletal `entrypoint.d` file 
that contains only it (and an import to the "main" 
`main.d`/`app.d`/whatever), so dub can safely exclude it in 
unittest builds without skipping any other tests I might have in 
the main file.

```
mainSourceFile "source/myproject/entrypoint.d"
```

```d
module myproject.entrypoint;

int main(string[] args)
{
     import myproject.main : run;
     return run(args);
}
```
