;; NAMING: "arc" is short for "archive" and does not refer specifically
|
|
|
|
|
;; to files whose name end in ".arc"
|
|
|
|
|
;;
|
|
|
|
|
;; This code does not decode any files internally, although it does
|
|
|
|
|
;; understand the directory level of the archives. For this reason,
|
|
|
|
|
;; you should expect this code to need more fiddling than tar-mode.el
|
|
|
|
|
;; (although it at present has fewer bugs :-) In particular, I have
|
|
|
|
|
;; not tested this under Ms-Dog myself.
|
|
|
|
|
;; -------------------------------------
|
|
|
|
|
;; INTERACTION: arc-mode.el should play together with
|
|
|
|
|
;;
|
|
|
|
|
;; * ange-ftp.el: Remote archives (i.e., ones that ange-ftp has brought
|
|
|
|
|
;; to you) are handled by doing all updates on a local
|
|
|
|
|
;; copy. When you make changes to a remote file the
|
|
|
|
|
;; changes will first take effect when the archive buffer
|
|
|
|
|
;; is saved. You will be warned about this.
|
|
|
|
|
;;
|
|
|
|
|
;; * dos-fns.el: (Part of Emacs 19). You get automatic ^M^J <--> ^J
|
|
|
|
|
;; conversion.
|
|
|
|
|
;;
|
|
|
|
|
;; arc-mode.el does not work well with crypt++.el; for the archives as
|
|
|
|
|
;; such this could be fixed (but wouldn't be useful) by declaring such
|
|
|
|
|
;; archives to be "remote". For the members this is a general Emacs
|
|
|
|
|
;; problem that 19.29's file formats may fix.
|
|
|
|
|
;; -------------------------------------
|
|
|
|
|
;; ARCHIVE TYPES: Currently only the archives below are handled, but the
|
|
|
|
|
;; structure for handling just about anything is in place.
