You will be happy to know that I agree :-)  I do like autogen,
I would have never thought that something as fixincludes can
be done (and maintained of course!) as M4, not to mention gen*.

But we were speaking of a Makefile, and M4 is a standard
for the build process (thanks? to autoconf), so the idea of a
M4 Makefile.tpl did not look so bizarre to me.  I think that
Makefile.in does belong in that small window.

And, Bruce, it would not look bizarre if Autogen were used to
implement Autoconf!
