| 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. | |

| 67 | ;; Special thanks to Bill Brodie <wbrodie@panix.com> for very useful tips | |
| 68 | ;; on the first released version of this package. | |
| 69 | ;; | |
| 70 | ;; This code is partly based on tar-mode.el from Emacs. | |
| 71 | ;; ------------------------------------- | |
| 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. | |
| 89 | ;; ------------------------------------- | |
| 90 | ;; SETUP: .emacs fodder: | |

| 95 | ;; (autoload 'archive-mode "arc-mode" "Major mode for editing archives." t) | |
| 96 | ;; | |
| 97 | ;; Furthermore, for msdog, you need to make sure that the archives are loaded | |
| 98 | ;; as binary files. For arc/zip/pak/lzh/zoo this is the default. | |
