25 | ;;; Commentary: | |
26 | ;; | |
27 | ;; NAMING: "arc" is short for "archive" and does not refer specifically | |
28 | ;; to files whose name end in ".arc" | |
29 | ;; | |
30 | ;; This code does not decode any files internally, although it does | |
31 | ;; understand the directory level of the archives. For this reason, | |
32 | ;; you should expect this code to need more fiddling than tar-mode.el | |
33 | ;; (although it at present has fewer bugs :-) In particular, I have | |
34 | ;; not tested this under Ms-Dog myself. | |
35 | ;; ------------------------------------- | |
36 | ;; INTERACTION: arc-mode.el should play together with | |
37 | ;; | |
38 | ;; * ange-ftp.el: Remote archives (i.e., ones that ange-ftp has brought | |
39 | ;; to you) are handled by doing all updates on a local | |
40 | ;; copy. When you make changes to a remote file the | |
41 | ;; changes will first take effect when the archive buffer | |
42 | ;; is saved. You will be warned about this. | |
43 | ;; | |
44 | ;; * dos-fns.el: (Part of Emacs 19). You get automatic ^M^J <--> ^J | |
45 | ;; conversion. | |
46 | ;; | |
47 | ;; arc-mode.el does not work well with crypt++.el; for the archives as | |
48 | ;; such this could be fixed (but wouldn't be useful) by declaring such | |
49 | ;; archives to be "remote". For the members this is a general Emacs | |
50 | ;; problem that 19.29's file formats may fix. | |
51 | ;; ------------------------------------- | |
52 | ;; ARCHIVE TYPES: Currently only the archives below are handled, but the | |
53 | ;; structure for handling just about anything is in place. | |

72 | ;; ARCHIVE STRUCTURES: | |
73 | ;; (This is mostly for myself.) | |
74 | ;; | |
75 | ;; ARC A series of (header,file). No interactions among members. | |
76 | ;; | |
77 | ;; LZH A series of (header,file). Headers are checksummed. No | |
78 | ;; interaction among members. | |
79 | ;; | |
80 | ;; ZIP A series of (lheader,fil) followed by a "central directory" | |
81 | ;; which is a series of (cheader) followed by an end-of- | |
82 | ;; central-dir record possibly followed by junk. The e-o-c-d | |
83 | ;; links to c-d. cheaders link to lheaders which are basically | |
84 | ;; cut-down versions of the cheaders. | |
85 | ;; | |
86 | ;; ZOO An archive header followed by a series of (header,file). | |
87 | ;; Each member header points to the next. The archive is | |
88 | ;; terminated by a bogus header with a zero next link. | |
