Software::License::PD - Public Domain pseudo-license
In legal circles, Public Domain is defined as the absence of copyright (and therefore precludes the need for any license). Artistic works enter the Public Domain in two common situations:
Some authors have chosen to disclaim all rights to their works and attempt to release them into the Public Domain. This is a particularly contentious issue because some jurisdictions do not recognize an author's perogative to disclaim all rights to their own work. In European countries, authors can abandon their claim to copyright, but not Reputation Rights (which prevent people from removing your name from your work, among other things).
While I have researched the issue to some extent, I am not a lawyer and am not qualified to provide legal advice. I have used this license for some of my own packages, but am unsure whether it would stand up in a court of law.
The Creative Commons Zero (CC0) license is an extremely liberal license, which confers rights similar to Public Domain to the extent permissible by law. However, Creative Commons does not recommend the application of their licenses to software, see: http://wiki.creativecommons.org/FAQ#Can_I_use_a_Creative_Commons_license_for_software.3F
Several notable Open Source software projects have been released into the Public Domain:
