OK, you simply do not target the same people as I though GNU
Hello should target.  Undoubtedly there are different levels of
Hello World, and I understand GNU Hello can only be one.

I met Akim two days ago, and when I mentioned GNU Hello being
revived his first answer was: "it would be nice to show an
example of Swig."  (That's because he had a hard time finding a
correct setup for his own package using Swig lately.)  Only then
did I explain him that the plan was instead to restrict the
functionalities.  Anyway the point is that experienced people
would like to see advanced examples, and newbies will certainly
want something they can toy with using their installed tools and
that is not encumbered by bleeding edge stuff or complex tricks
that make the maintenance easier once well understood.

I guess there is no way to please anybody.

I think I mentioned it already.  This is how I always did so
far, and probably how you did before gnulib: get a copy of the
files you need, stick them into your CVS, and update them
periodically.  This does not need to be done during bootstrap,
it can be done by a rule in the Makefile.

Why the *latest* files?  Why would you use the CVS version of
these files, and not also the CVS versions of Autoconf and
Automake?  I can't see the difference.  There are many bugs
fixed on the stable branch of CVS Automake that impact
everybody's package and yet people do not care and still use
whatever they have.  The same can hold for gnulib, hence the
Debian package (the existence of which I'm glad to learn).

I'm afraid that sounds like an argument to install gnulib too me :)

Simply do not use -f and you should be OK.  What are the files
that are installed by both tools anyway?  And why?  My feeling
is that we should arrange that no two tools install the same

That sounds good to me (although I don't understand what "in toto" means).
