THE PROGRAM), YOU INDICATE YOUR ACCEPTANCE OF THIS LICENSE, AND ALL ITS TERMS AND CONDITIONS FOR COPYING, DISTRIBUTING OR MODIFYING THE PROGRAM OR WORKS BASED ON IT. NOTHING OTHER THAN THIS LICENSE GRANTS YOU PERMISSION TO USE, MODIFY AND/OR DISTRIBUTE THE PROGRAM OR ITS DERIVATIVE WORKS. THESE ACTIONS ARE PROHIBITED BY LAW. IF YOU DO NOT ACCEPT THESE TERMS AND CONDITIONS, DO NOT USE, MODIFY AND/OR DISTRIBUTE THE PROGRAM. This license applies to the computer program(s) known as UCSD ACM SSH. The term "program" used in this license agreement refers to such program, and the term "work based on the program" means either the program or any derivative work of the program including it's output, such as a translation into another language, extending the program's functionality, use of parts of the program or it's output files or any modification of the program or it's output. The program is a copyrighted work whose copyright is held by Timothy Chen, Douglas Mak, and Mike Ayres ("the licensors"). 1. License terms Licensor hereby grants you the following rights, provided that you comply with all of the restrictions set forth in this license and provided further, that you distribute an unmodified copy of this license with the program: (a) You may copy and distribute the program's unaltered source code worldwide via any medium. Any distribution of the program or any programs containing source code of as well as any output created with the program must contain an appropriate credit and all additional materials included with the original distribution, including the unaltered license agreement. (b) You may use the program for non-commercial purposes only, meaning that the program must not be sold commercially as a separate product, as part of another product (bundled software) or project, or otherwise used for financial gain without a separate commercial license. Please see section 2, Restrictions, for details. (c) You may build derived versions of this software under the restrictions stated in section 2 (Restrictions) of this license. The derived versions must be clearly marked as such and must be called by a name other than UCSD ACM SSH. All derived versions of the program must be made freely available under the terms of this license. The licensors must be given the right to use the modified source code in their products without any compensation and without being required to separately name the parties whose modifications are being used. Credit for UCSD ACM SSH must be given to the licensors in all derived works. This does not affect your ownership of the derived work itself, and the intent is to assure proper credit for the licensors, not to interfere with your use of this derived work. 2. Restrictions (a) Distribution of the program or any work based on the program by a commercial organization to any third party is prohibited if any payment is made in connection with such distribution, whether directly (as in payment for a copy of the program) or indirectly (as in payment for some service related to the program, or payment for some product or service that includes a copy of the program without charge, or payment for some product or service the delivery of which requires for the recipient to retrieve/download or otherwise obtain a copy of the program; these are only examples, and not an exhaustive enumeration of prohibited activities). As an exception to the above rule, putting this program on CD-ROMs containing other free software is explicitly permitted even when a modest distribution fee is charged for the CD, as long as this software is not a primary selling argument for the CD. Three CDs must be sent to the authors without having the authors requesting it. (b) Activities other than copying, distribution and modification of the program are not subject to this license and they are outside it's scope. Functional use (running) of the program is not restricted. (c) You must meet all of the following conditions with respect to the distribution of any work based on the program: (i) All modified versions of the program, must carry prominent notice stating that the program has been modified. The notice must indicate who made the modifications and how the program's files were modified and the date of any change; (ii) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the program or any part thereof, to be licensed as a whole and at no charge to all third parties under the terms of this license; (iii) You must cause the program, at each time it commences operation, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty. The notice must also tell the user how to view the copy of the license included with the program, and state that users may redistribute the program only under the terms of this License; (iv) You must accompany any such work based on the program with the complete corresponding machine-readable source code, delivered on a medium customarily used for software interchange. The source code for a work means the preferred form of the work for making modifications to it; (v) If you distribute any written or printed material at all with the program or any work based on the program, such material must include either a written copy of this license, or a prominent written indication that the program or the work based on the program is covered by this license and written instructions for printing and/or displaying the copy of the License on the distribution medium; (vi) You may not change the terms in this License or impose any further restrictions on the recipient's exercise of the rights granted herein. 3. Reservation of Rights No rights are granted except as expressly set forth herein. You may not copy, modify, sublicense, or distribute the program or any parts of the the program, except as expressly provided under this license. Any attempt otherwise to copy, modify, sublicense or distribute the program or the HTML output files as a whole or in parts is void, and will automatically terminate your rights under this license. However, parties who have received copies, or rights, from you under this license will not have their licenses terminated as long as such parties remain in full compliance with the license. 4.
