Description

I think that it would be nice if we could display additional text about application if someone types MyApp --help, and additional help for verb if someone types MyApp Verb --help.

I know there is HelpText property on BaseAttribute. It is nice for communicating what given option does, however I think that it is not suitable for extended, in-depth explanation. I would see it like that:

MyApp.exe help
MyApp 1.0.0
Copyright (C) 2018 MyApp 

  verb1    Help text for verb 1
  verb2    Help text for verb 2
  help             Display more information on a specific command.
  version          Display version information.

Long explanation about app
MyApp.exe help verb1
MyApp 1.0.0
Copyright (C) 2018 MyApp 

  verb1    Help text for verb 1
  verb2    Help text for verb 2
  help             Display more information on a specific command.
  version          Display version information.
