FAQ, Q7: The example code makes no sense

[schittli]

Hello,

thanks a lot for sharing your great and useful work!

I probably have just a small issue to Q7 https://github.com/commandlineparser/commandline/wiki/How-To#q7 with this question:

How to Display version information on Application startup?

The example code looks like this:

var title=new HeadingInfo(programName:"My supper Application",version:"1.2.3; App-Server:3.6.7");
Console.WriteLine( title );

// The Result will be:
My supper Application 1.2.3; App-Server:3.6.7

This example code makes no sense, because the code does nothing more than we could achieve with this code:

Console.WriteLine( "My supper Application 1.2.3; App-Server:3.6.7" );

The example should display how we can modify the default help engine, including the default --version parameter handling

so that the default help automatically uses this new HeadingInfo 😀

Describe the bug It is a bug in the sense that the example code in the FAQ unfortunately does not show a relevant use-case on how to use HeadingInfo.

Expected behavior It would be great if the example code shows how we can slightly modify the default behavior of the help engine.

Thanks a lot, kind regards, Thomas
