VIGRA

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.)

   Standard Version of this Library without restriction, provided that
   you duplicate all of the original copyright notices, this license,

   of a collection of software, provided no more than a reasonable

   stating how and when you changed that file, and provided that you do
   at least ONE of the following:

       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
       organization. 

    c. make other distribution arrangements with the Copyright
       Holder.

   in object code or executable form without restriction.

7. The name of the Copyright Holder or the Library may not be used to 
   endorse or promote products derived from this software without 
   specific prior written permission.

   IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY SPECIAL, 
   INCIDENTAL, INDIRECT OR CONSEQUENTIAL DAMAGES OF ANY KIND OR ANY DAMAGES
   WHATSOEVER RESULTING FROM LOSS OF USE, DATA OR PROFITS, WHETHER
