;;; Commentary:
;; Usage: api-diff alist-file-A alist-file-B
;; Read in the alists from files ALIST-FILE-A and ALIST-FILE-B
;; and display four lists: old scheme, new scheme, old C, new C.
;;
;; For scheme programming, the (scripts api-diff) module exports
;; two procedures:
;; (diff-alists A-alist B-alist report)
;; (api-diff A-file B-file)
;; The latter implements the shell interface using the former.
;; REPORT is a proc that takes the above four lists. Its return
;; value is returned by `diff-alists'.
;;
;; Note that the convention is that the "older" alist/file is
;; specified first.
;;
;; TODO: When the annotations support it, also detect/report
;; procedure signature, or other simple type, changes.
