Software License

A software license is a license that grants permission to do things with computer software that would otherwise be prohibited by copyright law. For example, a software license might give permission to make copies of the software. A copyright holder may offer a software license unilaterally, or as part of a software license agreement with another party.

The license may include terms and conditions. If one does not follow the terms of the license, then he or she is subject to the normal restrictions of copyright law.
