Comment 2 for bug 334593

It's true that Yelp is a GNOME application however I believe that you may be wrong to say that because of this it doesn't support documentation for programs other than GNOME. For example, it provides access to all 'man' pages on my system, which are clearly not GNOME. Also, Yelp implements support for the Rarian documentation metadata system, which is an initiative of Freedesktop.org, aiming to be desktop-agnostic, i.e. it is not limited to only KDE or only GNOME (and this is a successor to Scrollkeeper, which was the same).

If Ubuntu doesn't provide a unified way for such -doc packages' files to be accessible from a unified 'librarian' program, then I will report this elsewhare. But I believe that Rarian is performing exactly this role.
