The DikuMUD License
*February 3rd, 2020 update: The DikuMUD authors Sebastian Hammer, Hans-Henrik Starfeldt, Katja Nyboe, and Michael Seifert have all agreed to make their DikuMUD work available under the LGPL license. We’ve been unable to get a hold of Tom Madsen, but we feel fairly confident that he would likewise agree to submit his work under LGPL. This means you can choose yourself if you want to use DikuMUD under the LGPL or the original license. Please note that derivative work isn’t automatically under LGPL. It would need to be re-released by its respective authors.
The original DikuMUD license is included below just for reference and can be found in the DikuMUD distributions.

DikuMud has been created by the above five listed persons in their spare time, at DIKU (Computer Science Instutute at Copenhagen University). You are legally bound to follow the rules described in this document. Rules: !! DikuMud is NOT Public Domain, shareware, careware or the like !! You may under no circumstances make profit on *ANY* part of DikuMud in any possible way. You may under no circumstances charge money for distributing any part of dikumud - this includes the usual $5 charge for "sending the disk" or "just for the disk" etc. By breaking these rules you violate the agreement between us and the University, and hence will be sued. You may not remove any copyright notices from any of the documents or sources given to you. This license must *always* be included "as is" if you copy or give away any part of DikuMud (which is to be done as described in this document). If you publish *any* part of dikumud, we as creators must appear in the article, and the article must be clearly copyrighted subject to this license. Before publishing you must first send us a message, by snail-mail or e-mail, and inform us what, where and when you are publishing (remember to include your address, name etc.) If you wish to setup a version of DikuMud on any computer system, you must send us a message , by snail-mail or e-mail, and inform us where and when you are running the game. (remember to include your address, name etc.) Any running version of DikuMud must include our names in the login sequence. Furthermore the "credits" command shall always cointain our name, addresses, and a notice which states we have created DikuMud. You are allowed to alter DikuMud, source and documentation as long as you do not violate any of the above stated rules. Regards, The DikuMud Group Note: We hope you will enjoy DikuMud, and encourage you to send us any reports on bugs (when you find 'it'). Remember that we are all using our spare time to write and improve DikuMud, bugs, etc. - and changes will take their time. We have so far put extremely many programming hours into this project. If you make any major improvements on DikuMud we would be happy to hear from you. As you will naturally honor the above rules, you will receive new updates and improvements made to the game.
