Conditions on Use of the AI Repository

In case it be determined by a court of competent jurisdiction that any provision herein contained is illegal, invalid or unenforceable, such determination shall solely affect such provision and shall not affect or impair the remaining provisions of this document.
  1. LACK OF WARRANTY.

    This software is made available "AS IS" and is distributed without warranties of any kind, either expressed or implied, including, without limitation, the implied warranties of merchantability and fitness for a particular purpose. No warranty is made about the software or its performance.

    Carnegie Mellon University and the repository maintainer(s) do not accept any responsibility to anyone for the consequences of using materials from the repository or for whether such materials serve any particular purpose or work at all.

    In no event will Carnegie Mellon University or the repository maintainer(s) be liable to you for damages, including lost profits, lost monies, lost revenue, or other special, incidental, consequential, indirect or punitive damages arising out of or in connection with the use or inability to use the software (including but not limited to loss of data or data being rendered inaccurate or losses sustained by third parties or a failure of the program to operate as documented), even if we have been advised of the possibility of such damages, or for any claim by any other party, whether in an action of contract, negligence, or other tortious action.

    Carnegie Mellon University and the repository maintainer(s) are under no obligation to provide any services, by way of maintenance, update, or otherwise.

    Inclusion of materials in the repository does not constitute an endorsement or recommendation of the materials and shall not be interpreted as such.

  2. EXPERIMENTAL NATURE OF THE MATERIALS.

    The materials included in the repository are to be considered experimental in nature. You assume any and all risk involved in using the software and agree to indemnify Carnegie Mellon University and the repository maintainer(s) against any and all actions arising from its use.

    USE OF THIS MATERIAL IS AT YOUR OWN RISK. We specifically deny any responsibility for the accuracy or quality of information contained in this distribution. We do not warrant the accuracy of the information provided. We do not warrant that the software, documentation, or the information provided will satisfy your requirements, or that the software and documentation are without defect or error, or that the operation of the software will be uninterrupted.

    By retrieving files from the repository and/or using the software (or authorizing any other person to do so) you signify your acceptance of these conditions. IF YOU DO NOT AGREE WITH THESE TERMS, DO NOT RETRIEVE FILES FROM THE REPOSITORY.

  3. FREELY DISTRIBUTABLE and FREE USAGE.

    Use and copying of the software and the preparation of derivative works based on this software are permitted, subject to the author's terms and conditions. Public domain software and software covered by the GNU General Public License automatically meet this definition. (To save space, a single copy of the GNU GPL has been placed in the file copying/gpl/gpl_2_0.txt.)

    Copyrighted software will be included if and only if the author(s) agree to let the software be distributed and used without fee. The authors of copyrighted software may place certain other restrictions on the software, such as restrictions against the commercialization of the software. See the following section for details.

  4. OTHER CONDITIONS.

    Some of the software packages included in the repository contain additional restrictions on their use. Conditions specific to a particular program or system will be included in a file named LICENSE, COPYING, COPYRIGHT, README or something similar (e.g., as a comment at the top of the source code files) in the tar file containing the program. You agree to adhere to these conditions. Any copyright notice or file must be left intact and included with any copy of the software or materials.

    In particular, some packages may contain restrictions against the commercialization of the software. Separate licensing is often available for companies wishing to commercialize the software or to incorporate the software into a commercial product. Contact the author(s) for details.

    Other packages may go one step further, and restrict the software license to non-commercial (education, research, and personal use) purposes. There is an important difference between "restrictions on commercialization" and "prohibition of commercial use". If you just want to prevent folks from selling your program or incorporating it into a commercial product, we recommend using the former.

    There may be other conditions, such restrictions against non-military use, restrictions against use in nuclear power plants or other safety-critical applications, and so on. Read the copyright notices in the packages for details.

    If we feel that an author's conditions unduly restrict the ability to distribute, use, and modify the software, we will not include it in the repository. The file copying/non_gpl/template.txt contains a template for an acceptable copyright notice (the file gpl_2_0.txt is also acceptable).

  5. COURTESIES.

    Producing free software takes time, effort, and money. There are certain courtesies that the authors request, and we strongly urge you to adhere to:
