Cool.  (I like ratpoison, and I wasn't aware it had been abandoned.  A
Guile-enabled ratpoison would be great.)

No problem, I'll add this.  Can you point to a specific 1.4.x commit, to
help with any extra bits that are needed, e.g. anything in configure.ac?

Well, indeed.  Let's make 2010 the year of repairing our divisions...

With Guile 1.9.x/2.0, we have a fantastic new base system that I think
will serve us well for some years.  With that in place, it would be
great to pull together all the Guile apps and extensions that are out
there, and showcase them working together and doing interesting things.
Plus, as far as possible, I hope we can find ways of making everything
work with older versions of Guile too.
