The documentation says that options can be made mandatory, but I can't see an example of how to do that.

I thought that maybe [Option(CommandOptionType.SingleValue)] would do this, but it doesn't.

Here is a sample. This should probably be explicitly called out in the docs, too.

CommandLineUtils/docs/samples/validation/attributes/Program.cs

Lines 14 to 16 in 7281ee9

    
           [Required] 
        
           [Option(Description = "Required. The message")] 
        
           private string Message { get; }

Oh, that's easy! Thanks.
I even went searching in here for Required and couldn't see it, cos that's the wrong place.
