This is Debian GNU/Linux's prepackaged version of the zoo archiver. This package was put together by James Troup from the original source obtained from: http://www.ibiblio.org/pub/packages/ccic/software/unix/utils/zoo210.tar.gz From May 1998 to July 2004 it was maintained by Petr Čech and currently it is maintained by Niklas Vainio Copyright and license: Zoo was written by Rahul Dhesi. He has now released it into the public domain: Return-Path: Date: Sat, 19 Jun 2004 13:50:26 -0700 (PDT) From: dhesi@rahul.net To: Niklas Vainio Subject: Re: License of Zoo Hi, the last release of the zoo archive program was marked entirely public domain, with no restrictions. I'm sure this statement will be found somewhere in the files in the sources. If not, I hope this email will suffice: everything in the zoo package is entirely public domain, with no restrictions whatsoever.
