I don't, but I would like to be able to run my code through the Emacs
formatter for publication purposes. ÂDoes anyone know how to do this
from the command line? ÂI do have Emacs installed.

emacs --batch FOO.scm --eval '(indent-region (point-min) (point-max))' -f 'save-buffer'Â

Argument order is important.
See http://stackoverflow.com/a/9825272/239657 for multi-file version, or just use a bash loop.Â

One indentation quirk that might surprise you is comment-only lines indented to far right.
Emacs uses convention of:
Â; comment on right, even on comment-only line.
Â;; comment indented as code.
Â;;; comment in column 0, even in middle of code.
