Open source software is computer software for which the human-readable
source code is made available under a copyright license (or
arrangement such as the public domain) that meets the Open Source
Definition. This permits users to use, change, and improve the
software, and to redistribute it in modified or unmodified form. It is
often developed in a public, collaborative manner. Open source
software is the most prominent example of open source development and
often compared to user generated content.
