       "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.

       "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

       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.
