The other thing I remember being caught up on, which was not a

@SOMETHING things ... I was not happy with:

+                            (string-replace-substring synopsis "@acronym" "")
+                            "@code" ""))
+                           80)

And then adding @command, @file, @acronym, etc. ... using increasingly
nested levels string-replace-substring would eventually become difficult
to read and surely there is a better way!

How about some regex:

(define regexp
  (delay (make-regexp "@(code|acronym|file)\\b")))

(define example "stuff @acronym @code @file")
(regexp-substitute/global #f (force regexp) example 'pre "" 'post)

$4 = "stuff   ".
