18 CircleMUD is licensed software. This file contains the text of the CircleMUD
19 license. If you wish to use the CircleMUD system in any way, or use any of
20 its source code, you must read this license and are legally bound to comply
21 with it.
22
23 CircleMUD is a derivative work based on the DikuMUD system written by Hans
24 Henrik Staerfeldt, Katja Nyboe, Tom Madsen, Michael Seifert, and Sebastian
25 Hammer. DikuMUD is also licensed software; you are legally bound to comply
26 with the original DikuMUD license as well as the CircleMUD license if you
27 wish to use CircleMUD.
28
29 Use of the CircleMUD code in any capacity implies that you have read,
30 understood, and agreed to abide by the terms and conditions set down by this
31 license and the DikuMUD license. If you use CircleMUD without complying with
32 the license, you are breaking the law.
33
34 Using CircleMUD legally is easy. In short, the license requires three things:
35
36 1) You must not use CircleMUD to make money or be compensated in any way.
37 2) You must give the authors credit for their work.
38 3) You must comply with the DikuMUD license.
39
40 That's it -- those are the main conditions set down by this license.
41 Unfortunately, past experience has shown that many people are not willing
42 to follow the spirit of the license, so the remainder of this document will
43 clearly define those conditions in an attempt to prevent people from
44 circumventing them.
45
46 The first condition says that you must not use CircleMUD to make money in
47 any way or be otherwise compensated. CircleMUD was developed in people's
48 uncompensated spare time and was given to you free of charge, and you must
49 not use it to make money. CircleMUD must not in any way be used to
50 facilitate your acceptance of fees, donations, or other compensation.
51 Examples include, but are not limited to the following:
52
53 -- If you run CircleMUD, you must not require any type of fee or donation
54 in exchange for being able to play CircleMUD. You must not solicit,
55 offer or accept any kind of donation from your players in exchange for
56 enhanced status in the game such as increased levels, character stats,
57 gold, or equipment.
58
59 -- You must not solicit or accept money or other donations in exchange for
60 running CircleMUD. You must not accept money or other donations from
61 your players for purposes such as hardware upgrades for running
62 CircleMUD.
63
64 -- You must not sell CircleMUD. You must not accept any type of fee in
65 exchange for distributing or copying CircleMUD.
66
67 -- If you are a CircleMUD administrator, You must not accept any type of
68 reimbursement for money spent out of pocket for running CircleMUD, i.e.,
69 for equipment expenses or fees incurred from service providers.
70
71
72 The second part of the license states that you must give credit to the
73 creators of CircleMUD. A great deal of work went into the creation of
74 CircleMUD, and it was given to you completely free of charge; claiming that
75 you wrote the MUD yourself is a slap in the face to everyone who worked to
76 bring you a high quality product while asking for nothing but credit for
77 their work in return.
78
79 Specifically, the following are required:
80
81 -- The text in the 'credits' file distributed with CircleMUD must be
82 preserved. You may add your own credits to the file, but the existing
83 text must not be removed, abridged, truncated, or changed in any way.
84 This file must be displayed when the 'credits' command is used from
85 within the MUD.
86
87 -- The "CIRCLEMUD" help entry must be maintained intact and unchanged, and
88 displayed in its entirety when the 'help circlemud' command is used.
89
90 -- The login sequence must contain the names of the DikuMUD and CircleMUD
91 creators. The 'login sequence' is defined as the text seen by players
92 between the time they connect to the MUD and when they start to play
93 the game itself.
94
95 -- This license must be distributed AS IS with all copies or portions of
96 the CircleMUD that you distribute, if any, including works derived from
97 CircleMUD.
98
99 -- You must not remove, change, or modify any notices of copyright,
100 licensing or authorship found in any CircleMUD source code files.
101
102 -- Claims that any of the above requirements are inapplicable to a particular
103 MUD for reasons such as "our MUD is totally rewritten" or similar are
104 completely invalid. If you can write a MUD completely from scratch then
105 you are encouraged to do so by all means, but use of any part of the
106 CircleMUD or DikuMUD source code requires that their respective licenses
107 be followed, including the crediting requirements.
108
109
110 The third part of the license simply states that you must comply with the
111 DikuMUD license. This is required because CircleMUD is a DikuMUD derivative.
112 The DikuMUD license is included below.
113
114
115 You are allowed to use, modify and redistribute all CircleMUD source code
116 and documentation as long as such use does not violate any of the rules
117 set down by this license.

179 This document contains the rules by which you can use, alter or publish
180 parts of DikuMud. DikuMud has been created by the above five listed persons
181 in their spare time, at DIKU (Computer Science Instutute at Copenhagen
182 University). You are legally bound to follow the rules described in this
183 document.
184
185 Rules:
186
187 !! DikuMud is NOT Public Domain, shareware, careware or the like !!
188
189 You may under no circumstances make profit on *ANY* part of DikuMud in
190 any possible way. You may under no circumstances charge money for
191 distributing any part of dikumud - this includes the usual $5 charge
192 for "sending the disk" or "just for the disk" etc.
193 By breaking these rules you violate the agreement between us and the
194 University, and hence will be sued.
195
196 You may not remove any copyright notices from any of the documents or
197 sources given to you.
198
199 This license must *always* be included "as is" if you copy or give
200 away any part of DikuMud (which is to be done as described in this
201 document).
202
203 If you publish *any* part of dikumud, we as creators must appear in the
204 article, and the article must be clearly copyrighted subject to this
205 license. Before publishing you must first send us a message, by
206 snail-mail or e-mail, and inform us what, where and when you are
207 publishing (remember to include your address, name etc.)
208
209 If you wish to setup a version of DikuMud on any computer system, you
210 must send us a message , by snail-mail or e-mail, and inform us where
211 and when you are running the game. (remember to include
212 your address, name etc.)
213
214
215 Any running version of DikuMud must include our names in the login
216 sequence. Furthermore the "credits" command shall always cointain
217 our name, addresses, and a notice which states we have created DikuMud.
218
219 You are allowed to alter DikuMud, source and documentation as long as
220 you do not violate any of the above stated rules.

229
230 Note:
231
232 We hope you will enjoy DikuMud, and encourage you to send us any reports
233 on bugs (when you find 'it'). Remember that we are all using our spare
234 time to write and improve DikuMud, bugs, etc. - and changes will take their
235 time. We have so far put extremely many programming hours into this project.
236 If you make any major improvements on DikuMud we would be happy to
237 hear from you. As you will naturally honor the above rules, you will receive
238 new updates and improvements made to the game.
