internal static class Program
{
    private static async Task Main(string[] args)
    {
        var runner = new Elib2EbookRunner();
        var exitCode = await runner.RunAsync(args);
        Environment.Exit(exitCode);
    }
}

пример запуска

var runner = new Elib2EbookRunner();

await runner.RunAsync(new[]
{
    "-u", "https://example.com/book/123",
    "-f", "epub"
});
