Only the package has a different name. The software name itself
is "GDM - GNOME Display Manager" in both cases.

Moreover README.Debian references 2.26, which was gdm, not gdm3.
This is confusing (bug reported, see bug 616603).

One may also wonder why one has "/usr/share/gdm" instead of
"/usr/share/gdm3". A bug?

Those who don't know GNOME may not know yelp, which is not a standard
way to get the manual. The standards are man pages and files under
/usr/share/doc/<package>.

Moreover, those who cannot start X or X applications because of the
XAUTHORITY problem (this was my case) will not be able to run yelp.

And why "yelp ghelp:gdm", not "yelp ghelp:gdm3"?
This is unintuitive.

Well, the man page is Debian-specific. I've reported bug 616612
(with patch).
