It has some rough edges but keeps my focus away from hacking on build
system files (which I tend to do far too much). So I'm digging it.

Thanks for the write up. I know most of the pieces, from reading the
manual. But I'm still trying to piece them together so this is very
helpful for me. Especially the "add-to-load-path" for geiser, as that is
what I was missing.
