license question
What do people think of the following licence? I think there are tons of
problems, and I'd like a laundry-list of them to bring to the author's
attention.
Analog is copyright (C) Stephen R. E. Turner 1995 - 1999.
This copyright applies to all source code, compiled code, documentation, and
graphics, except those parts written by other people (which are normally
copyright their authors).
This licence describes the conditions under which you may use, modify and
distribute version 3.32 of analog ("the program"). Except where stated,
the conditions of this licence apply equally to the source code for the
program, as well as to any compiled version. The form interface program is
part of the program for the purposes of this licence. If you are unable or
unwilling to accept these conditions in full, then, notwithstanding the
conditions in the remainder of this licence, you may not use, modify or
distribute the program at all. Text in square brackets is intended for
guidance only and does not form part of the licence in any way.
[Analog is free software. This licence is designed not to restrict your
freedom except insofar as is necessary to ensure that the program remains free
for all. If you want to do something that is against this licence, but within
the spirit of free software, then let's talk about it.]
1) Any use of analog which is illegal under international or local law is
forbidden by this licence. Any such action is the sole responsibility of
the person committing the action.
[Some jurisdictions regulate the collection and processing of data relating
to individuals, for example.]
2) The program may be used free of charge by any person or organisation to
whom it is made available, provided that that person accepts the conditions
of this licence.
3) The program may be copied and distributed by any person or organisation in
any way whatsoever, provided that any distribution is accompanied by a copy
of all the documentation pertaining to the program. You may not charge
for the program itself, only for reasonable costs of distributing the
program, and you must not do anything to suggest to the person to whom it is
distributed that analog is anything other than free software. Furthermore,
you may not charge for distributing a modified version of the program
unless the source code for the modified version, or a list of differences
between the modified version and the original version, is publicly and
freely available in machine readable form.
[If you distribute analog with a book or something like that, I'd be
pleased to receive a copy].
4) You may make a reasonable charge for either of the following services,
provided in each case that the third party is first made aware that analog
is free software and that the charge is therefore for your labour,
expertise and costs.
i) Installing the program on a computer on behalf of a third party;
ii) Running the program and providing output from it to a third party.
You may not charge for these services in connection with a modified version
of the program unless the source code for the modified version, or a list
of differences between the modified version and the original version, is
publicly and freely available in machine readable form.
5) You may modify the program in any way you wish provided that all of the
following conditions are met.
i) Any modification in the source code is clearly marked as such;
ii) No modification is made to my documentation;
[Any documentation needed on your changes must therefore be made in a
separate file].
iii) The VNUMBER string is changed to "3.32(modified)";
[This string can be found near the top of analhea2.h].
iv) You ensure that the HTML2.0 logo is never produced except when the
output is HTML2.0 conformant;
[This logo is produced in the function pagebot() in output2.c.
An HTML validator can be found at http://validator.w3.org/]
v) Any HTML output includes a link to the analog home page.
vi) All of the conditions of this licence, and no other conditions, apply to
your modified version.
You may claim copyright for the parts of the program you have written.
Changing the default options in the file analhead.h does not count as
modifying the program.
[You are encouraged to submit your changes to me for inclusion in subsequent
versions of analog].
6) You may use up to 1000 lines of my source code, modified or unmodified,
in your own program provided that both of the following conditions are met.
i) Authorship of my code is attributed to me, both in the source code for
your program, and in the documentation for your program if there is any;
ii) Your program must be used, modified and distributed as if it were a
modified version of analog under this licence, or as if it had been
distributed under the terms of version 2 or later of the Gnu General
Public Licence, or the Perl Artistic Licence, at your option.
[See http://www.gnu.org/copyleft/gpl.html and
http://language.perl.com/misc/Artistic.html respectively].
7) No warranty of any sort, expressed or implied, is provided in connection
with the program, including, but not limited to, implied warranties of
merchantibility or fitness for a particular purpose. Any cost, loss or
damage of any sort incurred owing to the malfunction or misuse of the
program or the inaccuracy of the documentation or connected with the program
in any other way whatsoever is the responsibility of the person who incurred
the cost, loss or damage. By using this program you give up any right to
seek any damages against me in connection with this program.
8) I, Stephen Turner, reserve the right to make exceptions to any of these
conditions, or alter these conditions, at any time. However, you may always
use these conditions instead of any altered version if you prefer.
[Note that this licence explicitly applies only to one version of
analog. Therefore, if I make new conditions in connection with a future
version, you do not then have the right to apply these conditions to that
version instead].
