ELXIS PUBLIC LICENSE (EPL)

Preamble

The Elxis Public License (EPL) is a free license for software and other kinds of works although it was initially written for Elxis CMS. The scope of this license is to make sure Elxis will always be an open source software released for free to the public in its original form. In order to protect Elxis from license violations from which, unfortunately, we have suffered in the past, EPL prohibits you from renaming Elxis, removing copyright notes and share modified copies of it. The terms and conditions described in this document, besides Elxis, applies to any software released under the EPL license.

Definitions

• To modify a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a modified version of the earlier work or a work based on the earlier work.
• A fork is a modified and/or renamed copy of the original software distributed and developed by other than the original author. EPL does not allow forks.
