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

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

Argument order is important.

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

One indentation quirk that might surprise you is comment-only lines indented to far right.

Emacs uses convention of:

; comment on right, even on comment-only line.

;; comment indented as code.

;;; comment in column 0, even in middle of code.
