|
|
;; 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.
