The term describes a group of copyleft licenses that apply to a variety of jobs such as software , the literature , the music and art . A copyleft license is based on the rules on copyright , which are seen by proponents of copyleft as a way of restricting the right to make and redistribute copies of a particular job, to ensure that each person receiving a copy or a derivative of a job, can in turn use, modify, and redistribute both the work itself as derived versions of it. Thus, and in a non-legal, copyleft can be considered as opposed to copyright .

For many people, copyleft is a technique that uses copyright as a means to subvert the restrictions imposed by the copyright traditionally on the spread and development of knowledge. With this approach, the copyleft is primarily a tool in a larger operation: the intention is to reverse those restrictions permanently.
