           0. Definitions
           "Program"       the work, either in binary or source form, that has a notice
                           attached to it stating that it has been released under this
                           license by the copyright holder.
           "Modification"  a derivative of the Program or any other work based on the Program
           "Linking"       using parts of the Program, or using parts of any other work,
                           thus creating a direct dependency between two Programs.
           "You"           the licensee
           "Runtime Environment"
                           the virtual machine or operating system required to run the
                           Program, as released by the Publisher or Creator of said
                           runtime environment. This includes any extentions or updates
                           for the runtime environment released by the Publisher or
                           Creator.

           1. License
           Herewith everybody is granted permission to copy and distribute verbatim copies
           of this document. The only restriction lies on changing the content, with the
           exception to translation of this license.

           This license applies to the Program that has been released under this license.
           The license only applies to copying, distribution and modification of the
           Program. Execution or output of the Program are not covered by this license,
           however the right for additional limitations on the use (that do not cover
           copying, distribution or modification) is granted to the copyright holder.
           This license is only valid when all terms in this license comply with the
           licenses of the dependecies of the Program. This includes the license of the
           possible required runtime envoirement.

           2. Copying and distribution
           You are granted to copy or distribute verbatim copies of the Program, on any
           medium, or in any format as you see fit. You are not limited to charging a fee
           for the physical act of transferring the copy, nor are you limited to provide
           warranty for the Program in return of a fee. Unless this is prohibited by the
           license of the Runtime Environment.

           Any distribution of the program should be accompanied with a verbatim copy of
           this license.

           3. Modification
           You are allowed to modify the Program, or portions of it, therefore making it a
           derivate of the Program. You are allowed to distribute your Modification under
           the following conditions:
                   - You must clearly state that it is a modification of the Program
                   - The original copyright notice must be kept intact
                   - The modified files must contain notices of the changes made to it
                   - The Modification must be released under the same license as the Program
                   - Distribution happens in compliance with section 2

           4. Source
           The original source of the Program or Modification must be freely available on
           request.

           5. Linking
           The Program or Modification may only link with other work that have been
           released as free software.

           The license grants exclusive right to link with any non-free part of the
           Runtime Environment, as provided by the publisher or creator of said Runtime
           Environment.
           Using addapted portions of source code available in the runtime environment
           in the Program is only allowed under the following terms:
                   - the addapted code is clearly marked to originate from the runtime
                     environment, quoting the original copyright.
                   - the following notice is added to the top of the file:
                     "This file contains portions of code from the runtime environment."

           6. NON WARRANTY
           THIS SOFTWARE DOES NOT COME WITH A WARRANTY OF ANY KIND, UNLESS NOTED OTHERWISE
           BY THE COPYRIGHT HOLDER OR WARRANTY PROVIDER. THE ENTIRE RISK OF THE PERFORMANCE
           AND QUALITY OF THE PROGRAM LIES WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
           YOU WILL ASSUME ALL COSTS FOR REQUIRED REPAIR OR CORRECTION.

## Differences with version 1.0

There is one major difference between this version and Legacy:OpenUnrealModLicense/Version 1.0 and that is that this version does not contain the clause

           The right to "port" the Program to another runtime environment is reserved for
           the copyright holder.

This clause was meaningless. Creating a port of the program is equal to creating a derivate. Creating a derivate of the program was already allowed. Therefor this clause has been removed from the license.
