## Note, ideally I would prefer it if this top level makefile did
## not get created by autoconf. As I find typing 'make' and relying
## on it to take care of all dependencies much more friendly than
## the multi-stage autoconf+make and also worry about updates to
## configure.in not getting propagated down the tree. (AGM) [I realise
## that this may not prove possible, but at least I tried.. Sigh.]
