Copyright, Licence and Warranty
MJSulib is copyright © 1989, 1992, 1997, 1999, 2005, 2012, 2015-2017 by Mike Spooner.
It is licensed free of charge, under the terms of version 2 (or, at your option,
any later version) of the GNU
General Public License.
I also do not charge
for "delivery" or "packaging" of the software, as it can be downloaded
directly from this site.
However, others may charge for delivery. For example, if a copy of
this software is delivered on a third-party CDROM, you may be charged a
delivery or packaging fee to
cover the costs of CDROM production or postage. You should not be charged
a licensing fee.
This software is provided with no warranty,
as described in the licence.
Liberty
In general, the licence grants you the freedom to:
- link the library with other GPL-licensed software to form binary executables or libraries
- study how the library works
- adapt it to your needs, or otherwise modify it
- redistribute copies of the software, either in it's original form, or
as modified by yourself, as long as any such distributed material, in whole, remains licenced under the terms of the GNU
General Public Licence.
The licence restricts you from denying such freedom to anybody else, whether
they received their copies from you or from another source.
As the software
is also copyrighted, you are not permitted to claim the original work as
your own (either for credo or ownership purposes), although you may copyright
or otherwise take credit for any modifications you make.
