|
|
29 ;; NAMING: "arc" is short for "archive" and does not refer specifically
|
|
|
30 ;; to files whose name end in ".arc"
|
|
|
31 ;;
|
|
|
32 ;; This code does not decode any files internally, although it does
|
|
|
33 ;; understand the directory level of the archives. For this reason,
|
|
|
34 ;; you should expect this code to need more fiddling than tar-mode.el
|
|
|
35 ;; (although it at present has fewer bugs :-) In particular, I have
|
|
|
36 ;; not tested this under Ms-Dog myself.
|
|
|
37 ;; -------------------------------------
|
|
|
38 ;; INTERACTION: arc-mode.el should play together with
|
|
|
39 ;;
|
|
|
40 ;; * ange-ftp.el: Remote archives (i.e., ones that ange-ftp has brought
|
|
|
41 ;; to you) are handled by doing all updates on a local
|
|
|
42 ;; copy. When you make changes to a remote file the
|
|
|
43 ;; changes will first take effect when the archive buffer
|
|
|
44 ;; is saved. You will be warned about this.
|
|
|
45 ;;
|
|
|
46 ;; * dos-fns.el: (Part of Emacs 19). You get automatic ^M^J <--> ^J
|
|
|
47 ;; conversion.
|
|
|
48 ;;
|
|
|
49 ;; arc-mode.el does not work well with crypt++.el; for the archives as
|
|
|
50 ;; such this could be fixed (but wouldn't be useful) by declaring such
|
|
|
51 ;; archives to be "remote". For the members this is a general Emacs
|
|
|
52 ;; problem that 19.29's file formats may fix.
|
|
|
53 ;; -------------------------------------
|
|
|
54 ;; ARCHIVE TYPES: Currently only the archives below are handled, but the
|
|
|
55 ;; structure for handling just about anything is in place.

80 ;; interaction among members.
|

81 ;;
|

82 ;; ZIP A series of (lheader,fil) followed by a "central directory"
|
|
|
83 ;; which is a series of (cheader) followed by an end-of-
|
|
|
84 ;; central-dir record possibly followed by junk. The e-o-c-d
|
|
|
85 ;; links to c-d. cheaders link to lheaders which are basically
|
|
|
86 ;; cut-down versions of the cheaders.

88 ;; ZOO An archive header followed by a series of (header,file).
