| 27 ;;; Commentary: | |
| 28 ;; | |
| 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. | |

| 74 ;; ARCHIVE STRUCTURES: | |
| 75 ;; (This is mostly for myself.) | |
| 76 ;; | |
| 77 ;; ARC A series of (header,file). No interactions among members. | |
| 78 ;; | |
| 79 ;; LZH A series of (header,file). Headers are checksummed. No | |
| 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. | |
| 87 ;; | |
| 88 ;; ZOO An archive header followed by a series of (header,file). | |
| 89 ;; Each member header points to the next. The archive is | |
| 90 ;; terminated by a bogus header with a zero next link. | |
