When I run command "vrms" in my Debian GNU/Linux, most of those non-free packages it finds are packers and/or unpackers. How about you? I like to listen to music modules made under Amiga and many of those modules are distributed in Aminet as LHA-archives. Sometimes I use DOS and its software may be distributed as ARJ- or RAR-archives.
Of course free GUI-software like FileRoller can unpack many formats, but actually most of them are just graphical front-ends for command-line archivers, both free and non-free. It is not very bad thing if we can't create archives in formats like ACE, ARJ, LHA or RAR with free software. But it is more important to have free software for unpacking of those archives. If we want to create new archives, we can always use free software like GNU tar, gzip and Bzip2 and tell other people to use some free or non-free software to unpack them. .tar-, .tar.gz-, .gz- and even .bz2- and .tar.bz2-files are well understood by many general-purpose archivers, like Winzip, PowerArchiver, UltimateZip and Stuffit. And GNU Tar, gzip and Bzip2 themselves have been ported to many Operating systems already (Unixes (both free and proprietary), Windows, MacOS, AmigaOS, OS/2 etc.)). I have collected many links to archivers in the end of this WWW-page: http://www.cc.jyu.fi/~juhtolv/mswordmail.html But now back to the original problem: * * * ZOO: /usr/share/doc/zoo/copyright says: "Currently, all extract-only programs, and all supporting utili- ties, are fully in the public domain and are expected to remain so for the forseeable future." So, where is that public-domain software for extracting ZOO-files? Somebody must find it and then create Debian-package of it. IMHO creating new ZOO-archives is not very important for us. * * * ARJ: Here is free implementation of it: http://testcase.newmail.ru/ It is under GNU GPL. I think it can also create ARJ-archives. * * * RAR: http://www.unrarlib.org/ This is kinda complicated. It is dual-licenced software. One of those licences is GNU GPL. But please read that FAQ: http://www.unrarlib.org/faq.html It is just a library for extracting RAR-files. So somebody must create some commandline tool that can unpack RAR-files and uses unrarlib for that. Then somebody can create Debian-package of both unrarlib and that commandline tool. I don't know, if source code of that library has some code from Eugene Roschal. * * * LHA: Here is relevant sections from /usr/share/doc/lha/copyright ---- Clip here ---- Translated License Statement (translated by GOTO Masanori <[EMAIL PROTECTED]>): It's free to distribute on the network, but if you distribute for the people who cannot access the network (by magazine or CD-ROM), please send E-Mail (Inter-Net address) to the author before the distribution. That's well where this software is appeard. If you cannot do, you must send me the E-Mail later. Original Source Code License Statement: /* Copyright (C) MCMLXXXIX Yooichi.Tagawa */ /* Modified Nobutaka Watazaki */ /* Thanks to H.Yoshizaki. (MS-DOS LHarc) */ ---- Clip here ---- I think, only way to get free unpacking software for LHA-files is to negotiate with those Japanese persons. Here are some URL of Japanese LHA-software: http://shibuya.cool.ne.jp/lha/ http://www2m.biglobe.ne.jp/~dolphin/lha/lha.htm How about contacting authors of AmigaOS-versions of LHA? http://lha.warped.com/index.html Maybe they could release those sources under some free licence and then somebody could port them to Unix? * * * ACE: http://www.winace.com/ They provide some statically linked Linux-binary for unpacking ACE-archives. If that file-format is not very secret, somebody might be able to create free unpacking-software for ACE-files. But feel free to negotiate with authors of WinAce. * * * ARC: This is very old archive-format. We only need some way to unpack those files. Fortunately, this was just announced at c.o.l.a: http://rus.members.beeb.net/nomarch.html It is meant to be free replacement for arc. It is under GNU GPL. It can also unpack Spark-files (common under Acorn Archimedes). * * * P.S: I don't subscribe to mailing-lists of Debian, so please Cc: your replies to me.
