/* * * 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. * * "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 ftp.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) accompany any non-standard executables with their corresponding Standard Version * executables, giving the non-standard executables non-standard names, and clearly * documenting 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. * * 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 whomever * generated them, and may be sold commercially, and may be aggregated with this Package. * * 7. C or perl subroutines supplied by you and linked into this Package shall not be considered part of * this Package. * * 8. The name of the Copyright Holder may not be used to endorse or promote products derived from * this software without specific prior written permission. * * 9.
