Here's the message
<https://def.fe.up.pt/pipermail/maxima-discuss/2012/042643.html> that
describes how to do this.  This is what I put into my startswank.lisp file,
and I load it in my .maximarc so that it's ready whenever I start maxima.

Then in emacs, M-x slime-connect.  Use the default for host and port.

And if you didn't, you could try :lisp (describe '$changevar)

This gives enough information of where to find $changevar.  I think this
only works for clisp, cmucl and sbcl.  I don't think the other lisps record
the source information.
