| 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 |

| 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. |
| |
