The VIGRA Artistic License
|
|
==========================
|
|
(modeled after the Perl Artistic License)
|
|
|
|
|
|
Preamble
|
|
--------
|
|
|
|
The intent of this document is to state the conditions under which
|
|
VIGRA may be copied, such that the author maintains some
|
|
semblance of artistic control over the development of the library,
|
|
while giving the users of the library the right to use and
|
|
distribute VIGRA in a more-or-less customary fashion, plus the
|
|
right to make reasonable modifications.
|
|
|
|
|
|
Definitions
|
|
-----------
|
|
|
|
"Copyright Holder" of the VIGRA library is
|
|
Ullrich Koethe, Cognitive Systems Group, University of Hamburg, Germany.
|
|
|
|
"Library" refers to the collection of files distributed by the
|
|
Copyright Holder under the name "VIGRA" (including this
|
|
LICENSE file and all accompanying documentation), and derivatives of that
|
|
collection of files created through textual modification.
|
|
|
|
"Standard Version" refers to the Library if it has not been
|
|
modified, or has been modified in accordance with the wishes of the
|
|
Copyright Holder as specified below.
|
|
|
|
"You" is you, if you're thinking about using, copying, modifying or
|
|
distributing this Library.
|
|
|
|
"Freely Available" means that no fee is charged for the item.
|
|
It also means that recipients of the item may redistribute it
|
|
under the same conditions they received it.
|
|
|
|
"Reasonable copying fee" is whatever you can justify on the basis
|
|
of media cost, duplication charges, time of people involved, and so
|
|
on. (You will not be required to justify it to the Copyright Holder,
|
|
but only to the computing community at large as a market that must
|
|
bear the fee.)
|
|
|
|
|
|
License terms
|
|
-------------
|
|
|
|
1. You may make and give away verbatim copies of the

3. You may apply bug fixes and portability fixes
|

derived from the Public Domain or from the Copyright Holder. A

at least ONE of the following:
|
|
|
|
a. place your modifications in the Public Domain or otherwise
|
|
make them Freely Available, for example by allowing the Copyright
|
|
Holder to include your modifications in the Standard Version of
|
|
the Library.
|
|
|
|
b. use the modified Library only within your corporation or
|
|

7. The name of the Copyright Holder or the Library may not be used to
|

endorse or promote products derived from this software without
