Unless I'm missing something, but it's not as simple as that. You might have a summary that spans multiple lines (for code readability) but you really want the newlines removed in the help description, e.g.:

/// <summary>
/// This is a really long summary because my app is really great and I want
/// to say lots of great things about it in this summary so people will use it
/// all the time and then I will get famous.
/// </Summary>

So how do you to tell DragonFruit that it should keep the newline? You could use a special character e.g. -:

/// <summary>
/// - This is a really great app
/// - You can use it for all the things
/// </Summary>

But then you should support multiple levels of indentation, bullet points and so forth? Is this really worth it? For instance, node -h and npm -h don't have a description and dotnet -h has a super small description : Execute a .NET SDK command.

I don't think it needs to be complicated. just look for a newline? I don't think there is any need for detailed formatting in comments but I do see the need for line returns

But the newline won't work in every case - if you have a long Summary and have used newlines for code readability, you want these removed in the help command.

.NET XML documentation supports the <para> tag for explicitly specifying paragraphs. When it is compiled, separate paragraphs are separated by line breaks.

tags do not create newlines in --help from dragon fruit. That would be great if they did!

I ran the test, and saw that if there was only one para tag it did create the new line? But multiple it didn't, because it uses Value?
I don't have time to look into this further, but I did open a PR (only to my forks master, I don't want to clutter up the offical repo with a PR if I don't intend on following up), and anyone can feel free to take a look and base further work in this area on that.

I do think proper handling of doc string tags (list, para, etc) would help create nice help messages, which are nice to have.
