artistic license

The Artistic License (version 1.0) is a software license used for certain free and open source software packages, most notably the standard implementation of the Perl programming language and most CPAN modules, which are dual-licensed under the Artistic License and the GNU General Public License (GPL). The original Artistic License was written by Larry Wall. The name of the license is a reference to the concept of artistic license.

Artistic license (also known as art licenselo, historical license, dramatic license, poetic license, narrative license, licentia poetica, or simply license) is a colloquial term, sometimes a euphemism, used to denote the distortion of fact, alteration of the conventions of grammar or language, or rewording of pre-existing text made by an artist in the name of art.
