;;; Author: Thien-Thi Nguyen

;;; Commentary:

;; Usage: punify FILE1 FILE2 ...
;;
;; Each file's forms are read and written to stdout.
;; The effect is to remove comments and much non-essential whitespace.
;; This is useful when installing Scheme source to space-limited media.
;;
;; Example:
;; $ wc ./punify ; ./punify ./punify | wc
;;     89     384    3031 ./punify
;;      0      42     920
;;
;; TODO: Read from stdin.
;;       Handle vectors.
;;       Identifier punification.
