;; We introduce a wrapper for ls so that we can inspect generated files. We
;; need a ttag to call sys-call, but this should be a sound extension of ACL2
;; as it does not muck with any system internals.

;; I've complained before that ACL2's sys-call does not provide a standard
;; interface across Lisps, but it has not been standardized. So, calling
;; ls, which ought to be a really simple thing, is not and is probably buggy
;; in some cases. This sort of shit is really lame, and makes me want to
;; use a different language. In the meantime, we have this hacky solution.
#+gcl
;; GCL needs the filename to be quoted, or it won't handle filenames with
;; spaces correctly.

whose names include quotes on GCL.~%")

#+allegro
;; Allegro is completely fucked. Whether or not you quote the string, the
;; spaces within it will be interpreted as argument separators. So, I don't
;; know of any way to actually say ls "hello world.txt" in allegro.
