* The "Artistic License" *
* *
* Preamble *
* *
* The intent of this document is to state the conditions under which a *
* Package may be copied, such that the Copyright Holder maintains some *
* semblance of artistic control over the development of the package, *
* while giving the users of the package the right to use and distribute *
* the Package in a more-or-less customary fashion, plus the right to make *
* reasonable modifications. *
* *
* Definitions: *
* *
* "Package" refers to the collection of files distributed by the *
* Copyright Holder, and derivatives of that collection of files *
* created through textual modification. *
* *
* "Standard Version" refers to such a Package if it has not been *
* modified, or has been modified in accordance with the wishes *
* of the Copyright Holder as specified below. *
* *
* "Copyright Holder" is whoever is named in the copyright or *
* copyrights for the package. *
* *
* "You" is you, if you're thinking about copying or distributing *
* this Package. *
* *
* "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.) *
* *
* "Freely Available" means that no fee is charged for the item *
* itself, though there may be fees involved in handling the item. *
* It also means that recipients of the item may redistribute it *
* under the same conditions they received it. *
* *
* 1. You may make and give away verbatim copies of the source form of the *
* Standard Version of this Package without restriction, provided that you *
* duplicate all of the original copyright notices and associated disclaimers. *
* *
* 2. You may apply bug fixes, portability fixes and other modifications *
* derived from the Public Domain or from the Copyright Holder. A Package *
* modified in such a way shall still be considered the Standard Version. *
* *
* 3. You may otherwise modify your copy of this Package in any way, provided *
* that you insert a prominent notice in each changed file stating how and *
* when you changed that file, and provided that you do at least ONE of the *
* following: *
* *
* a) place your modifications in the Public Domain or otherwise make them *
* Freely Available, such as by posting said modifications to Usenet or *
* an equivalent medium, or placing the modifications on a major archive *
* site such as uunet.uu.net, or by allowing the Copyright Holder to include *
* your modifications in the Standard Version of the Package. *
* *
* b) use the modified Package only within your corporation or organization. *
* *
* c) rename any non-standard executables so the names do not conflict *
* with standard executables, which must also be provided, and provide *
* a separate manual page for each non-standard executable that clearly *
* documents how it differs from the Standard Version. *
* *
* d) make other distribution arrangements with the Copyright Holder. *
* *
* 4. You may distribute the programs of this Package in object code or *
* executable form, provided that you do at least ONE of the following: *
* *
* a) distribute a Standard Version of the executables and library files, *
* together with instructions (in the manual page or equivalent) on where *
* to get the Standard Version. *
* *
* b) accompany the distribution with the machine-readable source of *
* the Package with your modifications. *
* *
* c) give non-standard executables non-standard names, and clearly *
* document the differences in manual pages (or equivalent), together *
* with instructions on where to get the Standard Version. *
* *
* d) make other distribution arrangements with the Copyright Holder. *
* *
* 5. You may charge a reasonable copying fee for any distribution of this *
* Package. You may charge any fee you choose for support of this *
* Package. You may not charge a fee for this Package itself. However, *
* you may distribute this Package in aggregate with other (possibly *
* commercial) programs as part of a larger (possibly commercial) software *
* distribution provided that you do not advertise this Package as a *
* product of your own. You may embed this Package's interpreter within *
* an executable of yours (by linking); this shall be construed as a mere *
* form of aggregation, provided that the complete Standard Version of the *
* interpreter is so embedded. *
* *
* 6. The scripts and library files supplied as input to or produced as *
* output from the programs of this Package do not automatically fall *
* under the copyright of this Package, but belong to whoever generated *
* them, and may be sold commercially, and may be aggregated with this *
* Package. If such scripts or library files are aggregated with this *
* Package via the so-called "undump" or "unexec" methods of producing a *
* binary executable image, then distribution of such an image shall *
* neither be construed as a distribution of this Package nor shall it *
* fall under the restrictions of Paragraphs 3 and 4, provided that you do *
* not represent such an executable image as a Standard Version of this *
* Package. *
* *
* 7. C subroutines (or comparably compiled subroutines in other *
* languages) supplied by you and linked into this Package in order to *
* emulate subroutines and variables of the language defined by this *
* Package shall not be considered part of this Package, but are the *
* equivalent of input as in Paragraph 6, provided these subroutines do *
* not change the language in any way that would cause it to fail the *
* regression tests for the language. *
* *
* 8. Aggregation of this Package with a commercial distribution is always *
* permitted provided that the use of this Package is embedded; that is, *
* when no overt attempt is made to make this Package's interfaces visible *
* to the end user of the commercial distribution. Such use shall not be *
* construed as a distribution of this Package. *
* *
* 9. The name of the Copyright Holder may not be used to endorse or promote *
* products derived from this software without specific prior written *
* permission. *
* *
* 10. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR *
* IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED *
* WARRANTIES OF MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE. *
* *
* The End *
* *
