The unarj package does not include various *.txt files from inside the upstream archive. Of these, unarj.txt contains licensing information. I'd suggest including that and technote.txt in the package. OTOH, FYI: the license of unarj sounds quite a bit like the one of pine to me, and pine was removed from Fedora Core due to legal issues.
In addition to unarj.txt, run unarj without arguments to see more license terms.
Wow, that's a rather odd license: One of the conditions for commercial redistribution seems to be that the "...user must fully understand that UNARJ does not have the long usage history that ARJ does." I certainly didn't "fully understand" that before reading the license. :( I guess you would need to make the thing display a warning message each time it's run or something. Although, such a warning message would be almost an advertisement for the commercial ARJ. I'm not sure unarj can really be called "open source". (If it can be, then I have two other things to mention: (a) The latest version is 2.65, not 2.63a (b) ARJ archives are rare enough these days (IMO) that this package probably belongs in Extras, not Core. If the package isn't going to be dropped completely, then I guess I could file another bug for (a) and mention (b) on the mailing lists.)
FWIW, I already have an update to 2.65 available from http://cachalot.mine.nu/2/SRPMS.lvn/ . My guess is that this will be removed from Core, and livna.org would be the best new home for it :) * Wed Sep 1 2004 Ville Skyttä <ville.skytta at iki.fi> - 2.65-0.lvn.1 - Update to 2.65. - Add technote.txt and unarj.txt to docs. - Honor $RPM_OPT_FLAGS. By the way, the 2.65 source is shipped as a "self-extracting" .exe, which can be unpacked on Linux using... unarj :P
ARJ archives were popular on MSDOS about 15 years ago, but I don't really see the usefullness of them on a modern Linux system. This is the type of functionality I'd expect us to remove and stuff in Fedora Extras, or if the license sucks, to just dump it. The impact on users is likely very minimal.
unrar would be more useful to have, and I think it might even qualify as open source ;)
I'll take unrar if we remove unarj from the distro. I've actually had to use unrar in the past decade.
I think adding unrar would be nice. Coincidentally, I've been maintaining an unrar rpm for about 18 months now, feel free to grab it: http://rpm.livna.org/fedora/2/i386/SRPMS.stable/unrar-3.4.1-0.lvn.1.2.src.rpm
Package has been removed from Fedora Core 3.
