/******************************************************************************\ * * * SimpleCUDD library (www.cs.kuleuven.be/~theo/tools/simplecudd.html) * * SimpleCUDD was developed at Katholieke Universiteit Leuven(www.kuleuven.be) * * * * Copyright T. Mantadelis and Katholieke Universiteit Leuven 2008 * * * * Author: Theofrastos Mantadelis * * File: simplecudd.h * * * ******************************************************************************** * * * 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.
