CircleMUD License

CircleMUD is licensed software. This file contains the text of the CircleMUD
|
|
license. If you wish to use the CircleMUD system in any way, or use any of
|
|
its source code, you must read this license and are legally bound to comply
|
|
with it.
|
|
|
|
CircleMUD is a derivative work based on the DikuMUD system written by Hans
|
|
Henrik Staerfeldt, Katja Nyboe, Tom Madsen, Michael Seifert, and Sebastian
|
|
Hammer. DikuMUD is also licensed software; you are legally bound to comply
|
|
with the original DikuMUD license as well as the CircleMUD license if you
|
|
wish to use CircleMUD.
|
|
|
|
Use of the CircleMUD code in any capacity implies that you have read,
|
|
understood, and agreed to abide by the terms and conditions set down by this
|
|
license and the DikuMUD license. If you use CircleMUD without complying with
|
|
the license, you are breaking the law.
|
|
|
|
Using CircleMUD legally is easy. In short, the license requires three things:
|
|
|
|
1) You must not use CircleMUD to make money or be compensated in any way.
|
|
2) You must give the authors credit for their work.
|
|
3) You must comply with the DikuMUD license.
|
|
|
|
That's it -- those are the main conditions set down by this license.
|
|
Unfortunately, past experience has shown that many people are not willing
|
|
to follow the spirit of the license, so the remainder of this document will
|
|
clearly define those conditions in an attempt to prevent people from
|
|
circumventing them.
|
|
|
|
The first condition says that you must not use CircleMUD to make money in
|
|
any way or be otherwise compensated. CircleMUD was developed in people's
|
|
uncompensated spare time and was given to you free of charge, and you must
|
|
not use it to make money. CircleMUD must not in any way be used to
|
|
facilitate your acceptance of fees, donations, or other compensation.
|
|
Examples include, but are not limited to the following:
|
|
|
|
-- If you run CircleMUD, you must not require any type of fee or donation
|
|
in exchange for being able to play CircleMUD. You must not solicit,
|
|
offer or accept any kind of donation from your players in exchange for
|
|
enhanced status in the game such as increased levels, character stats,
|
|
gold, or equipment.
|
|
|
|
-- You must not solicit or accept money or other donations in exchange for
|
|
running CircleMUD. You must not accept money or other donations from
|
|
your players for purposes such as hardware upgrades for running
|
|
CircleMUD.
|
|
|
|
-- You must not sell CircleMUD. You must not accept any type of fee in
|
|
exchange for distributing or copying CircleMUD.
|
|
|
|
-- If you are a CircleMUD administrator, You must not accept any type of
|
|
reimbursement for money spent out of pocket for running CircleMUD, i.e.,
|
|
for equipment expenses or fees incurred from service providers.
|
|
|
|
|
|
The second part of the license states that you must give credit to the
|
|
creators of CircleMUD. A great deal of work went into the creation of
|
|
CircleMUD, and it was given to you completely free of charge; claiming that
|
|
you wrote the MUD yourself is a slap in the face to everyone who worked to
|
|
bring you a high quality product while asking for nothing but credit for
|
|
their work in return.
|
|
|
|
Specifically, the following are required:
|
|
|
|
-- The text in the 'credits' file distributed with CircleMUD must be
|
|
preserved. You may add your own credits to the file, but the existing
|
|
text must not be removed, abridged, truncated, or changed in any way.
|
|
This file must be displayed when the 'credits' command is used from
|
|
within the MUD.
|
|
|
|
-- The "CIRCLEMUD" help entry must be maintained intact and unchanged, and
|
|
displayed in its entirety when the 'help circlemud' command is used.
|
|
|
|
-- The login sequence must contain the names of the DikuMUD and CircleMUD
|
|
creators. The 'login sequence' is defined as the text seen by players
|
|
between the time they connect to the MUD and when they start to play
|
|
the game itself.
|
|
|
|
-- This license must be distributed AS IS with all copies or portions of
|
|
the CircleMUD that you distribute, if any, including works derived from
|
|
CircleMUD.
|
|
|
|
-- You must not remove, change, or modify any notices of copyright,
|
|
licensing or authorship found in any CircleMUD source code files.
|
|
|
|
-- Claims that any of the above requirements are inapplicable to a particular
|
|
MUD for reasons such as "our MUD is totally rewritten" or similar are
|
|
completely invalid. If you can write a MUD completely from scratch then
|
|
you are encouraged to do so by all means, but use of any part of the
|
|
CircleMUD or DikuMUD source code requires that their respective licenses
|
|
be followed, including the crediting requirements.
|
|
|
|
|
|
The third part of the license simply states that you must comply with the
|
|
DikuMUD license. This is required because CircleMUD is a DikuMUD derivative.
|
|
The DikuMUD license is included below.
|
|
|
|
|
|
You are allowed to use, modify and redistribute all CircleMUD source code
|
|
and documentation as long as such use does not violate any of the rules
|
|
set down by this license.

This document contains the rules by which you can use, alter or publish
|
|
parts of DikuMud. 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.
