The new 'manual_section'/--manual-section allows us to specify a desired manual page version.
The new 'manual_title'/--manual--title option allows us to specify manual page title.
The 'version'/--version has a better documentation now, and is fixed so it has the effect.
The 'description'/--description now has the needed effect, and better documentation.
The 'long_description' is deprecated, unused and hidden. It doesn't make sense to mixup project-description with the utility description. Utility description is directly in the Argparse object.
