That's "The top level Makefile.in".  No automake at the top level (there 
are almost no actual files to deal with, so automake is an unnecessary 
complication).

That it is.  I don't think it contains any feature creep; all I've used 
so far are IF/ELSE, FOR, and plain old substitutions.  (Albeit lots and 
lots of those, nested, which is why I'm using AutoGen.)  But it might in 
the future.  :-)

I wouldn't be at all surprised if any AutoGen version in the 5.x series 
worked for Makefile.tpl.  (Nothing earlier, obviously!)

Makefile.tpl doesn't use anything guile-version-specific at the moment, 
so it simply requires whatever version AutoGen requires.
