Well, my personal preference has always been to include whatever
documentation a package has, whether it be man pages or supplementary
HTML documentation. I figure if space is really an issue for a
particular user, they can delete the documentation if they wish.
As a maintainer, I'd rather provide the user with the complete package.
If the original software includes documentation, then in my opinion
the package I produce won't be complete unless I include the original
documentation.
In my opinion, distributing software without documentation is like
selling hardware without manuals. Sure, you can *still* use it, but
it's really a pain to download the documentation if you'd like explore
additional features or configurations.
AMEN!
