This Stack Overflow question lists some current options for interacting
with Scheme from Emacs:
<https://stackoverflow.com/questions/110911/what-is-the-closest-thing-to-slime-for-scheme>

It just occurred to me that Common Lisp and Scheme (and perhaps even
Clojure?) could probably be served by the same Emacs package. And in
those Stack Overflow answers, people point out that some Schemes already
work with SLIME. So my favorite option would be to team up with the
SLIME people since they have already put years of work into solving
these problems. (But I'm a bit biased since I like all Lisps about
equally so I'm always excited about opportunities for cross-Lisp work...)

Is someone here familiar with the differences between SLIME and Geiser?
At face value they seem to cover the same ground, but one originally
designed for CL and the other for Scheme.
