This is a Debian prepackaged version of the shareware abuse sound effects. This package was put together by Joey Hess , using sources from: ftp://ftp.cdrom.com/pub/abuse/abuse200.zip Author: Bobby Prince I contacted the author in May 2004 about the licensing: > Hello, I am a member of the Debian project (http://www.debian.org/) > which aims to build a free, full-featured operating system. By > "free", we basically mean that the user gets a right to use, > modify and redistribute (even resell) the software at will > (http://www.debian.org/social_contract#guidelines). > > The old Abuse game, for which you created the sound effects, > was released to the public domain by Crack.com, which means we can > distribute it with Debian. However we cannot distribute the sound files > because they still have your exclusive copyright with no redistribution > clause. Would you be favourable to relicensing these sound effects so > that we can distribute Abuse? If you have special requirements and are > not fond of public domain, we can discuss a license that will please > you while being free for Debian. This is the answer I got on May 16th 2004: > While the sfx are not in the public domain, you have my permission to use > them for your purposes below. I'll check your operating system out -- it > sounds interesting :-) Though the meaning of "your purposes below" is not entirely clear, this clearly gives permission to redistribute the files. I asked the author for clarification (and proposed to use a BSD-like license) but have not got an answer so far.
