ATOM ACADEMIC LICENCE Motivation and Preamble The ATOM package has been devised for its general use in research within the academic community. Some conditions have been defined for the use, distribution, and modification of the package. 1. DEFINITIONS "The ATOM package" is the suite of software, including the ATOM code itself, but also all other software, documentation, scripts, and ancillary support material distributed as a single entity. This Licence covers the entirety of said data. "The Authors" are: -- Sverre Froyen -- Norman J. Troullier -- Jose Luis Martins -- Luis C. Balbás -- José M. Soler -- Alberto Garcia "The Developers" are (currently) Alberto Garcia. "The Copyright-Holder" is the set of Authors. The valid distributors of the ATOM package ("The Distributors") are the Developers as specified above. The Licensee is the person (never an institution) to whom the ATOM package is distributed (under the terms of this Licence) by the Distributors; they are bound by this agreement. 2. NO WARRANTY There is no warranty for any part of the ATOM package. The ATOM package is provided "as-is" without warranty of any kind, either express or implied, including but not limited to the implied warranties of merchantability or fitness for a particular purpose. In no event shall the Distributors be liable for any direct, indirect, incidental, special, exemplary, or consequential damages (including, but not limited to, procurement of substitute goods or services; loss of use, data, or profits; or business interruption) however caused and on any theory of liability, whether in contract, strict liability, or tort (including negligence or otherwise) arising in any way out of the use of this software, even if advised of the possibility of such damage. The entire risk as to the quality or performance of the program, or any action the Licensee may take based on the output of any part of the ATOM package, is with the Licensee. 3. Limitation of Usage The use of the ATOM package under the present Licence is restricted to academic purposes, i.e., leading to open publication of results, with neither withhold of information nor intentional delay in publication. The above-mentioned right to use the code is extensive to the members of the research group of the Licensee as long as the use is in collaboration with the Licensee leading to co-authored publication(s). 4. Support The present Licence does not imply support services of any kind to the Licensee by the Distributors, including, but not limited to, installation, compilation and use of the software in the package. 5. Modification Licensees are permitted to modify ATOM for their own private use; in any paper containing results wholly or partially derived from the use of a modified version, the authors are required to state that a privately modified version is used, and satisfy the conditions of use stated above. The Developers encourage Licensees to submit their modifications of the ATOM package to them, so that the ATOM package does not fork, and furthermore so that the package can be improved for all users. Licensees can thereby benefit from the ulterior developments of ATOM. To this end, the Developers wish to encourage Licensees to make any modifications to the ATOM package in as modular a fashion as possible: for example, interacting via files, or via well-defined interface calls. This permits maintenance of these modifications as a separate entity in many cases, and may allow their separation from ATOM and distribution as a separate piece of software: in that case, such software is not subject to this Licence, and the authors of the separate software are free to choose any licensing terms they desire. However, if a given modification must be incorporated directly into the ATOM package, the author(s) of any such modifications must provide a perpetual, royalty-free, irrevocable license to the Copyright-Holder, to further modify their modifications ("the Contributed Code") as may prove necessary for the future development of ATOM, and to distribute the Contributed Code (in its original or any later modified form) as part of the ATOM package. The Developers, in the interests of maintaining the efficiency of the ATOM package and the modularity of its code base, actively encourage all those considering modifications to the ATOM package to discuss their planned modifications with the Developers beforehand. 6. Redistribution The Authors reserve the exclusive right to distribute the ATOM package. Licensees have no right to distribute the ATOM package, a modified or alternative version thereof, or any other program making direct use of parts of the ATOM package, without the prior written consent of the Distributors. 7. All Other Rights All other rights not explicitly mentioned in this document are reserved. In particular, the Authors reserve all rights to resolve any and all conflicts arising in the development and distribution policies of the ATOM package. Without accepting the Licence, a prospective Licensee does not have the right to use or modify the ATOM package. Everyone is permitted to copy and distribute verbatim copies of this Licence document, but changing it is not permitted.
