In the following, the term ``the authors'', refers to P. Blaha, K. Schwarz, G. K. H. Madsen, D. Kvasnicka and J. Luitz at the above address. ``Program'' shall mean that copyrighted APW+LO code (in source and object form) comprising the computer programs known as WIEN2k or the graphical user interface w2web.


I will adhere to the following conditions upon receipt of the program:

  1. All title, ownership and rights to the program or to copies of it remain with the authors, irrespective of the ownership of the media on which the program resides.

  2. I will not supply a copy of the code to anyone for any reason whatsoever. This in no way limits my making copies of the code for backup purposes, or for running on more than one computer system at my institution (it is a site license for the registered group). I will refer any request for copies of the program to the authors.

  3. I will not incorporate any part of WIEN2k or w2web into any other program system, without prior written permission of the authors.

  4. I will keep intact all copyright notices.

  5. I understand that the authors supply WIEN2k and w2web and its documentation on an ``as is'' basis without any warranty, and thus with no additional responsibility or liability. I agree to report any difficulties encountered in the use of WIEN2k or w2web to the authors.

  6. In any publication in the scientific literature I will reference the program as follows:

    P. Blaha, K. Schwarz, G. Madsen, D. Kvasnicka and J. Luitz, WIEN2k, An Augmented Plane Wave + Local Orbitals Program for Calculating Crystal Properties (Karlheinz Schwarz, Techn. Universität Wien, Austria), 2001. ISBN 3-9501031-1-2

    Please enter your publications with WIEN2k on our web-page for ``papers'', so that they are included in the list of WIEN-publications.

  7. It is understood that modifications of the WIEN2k or the w2web code can lead to problems where the authors may not be able to help.

    It would be appreciated if useful modifications or major extensions are reported to the authors.

  8. I understand that support for running the program can not be provided in general, except on the basis of a joint project between the authors and the research partner.
