The current package is based on a code which was originally developed at the University of Graz within the EU Research and Training Network EXC!TiNG, copyright by Kay Dewhurst, Sangeeta Sharma, and Claudia Ambrosch-Draxl. Beta releases have been made available under the gpl license at source forge.

In 2009, the code has split into two branches. exciting is primarily developed at the University of Leoben in the group of Claudia Ambrosch-Draxl. The second branch, named ELK, is being developed by Kay Dewhurst and Sangeeta Sharma in the group of Hardy Gross at the Free University, Berlin.

We want to thank at this point everyone who has contributed to one of the previous versions. A list of names can be found at http://exciting.sourceforge.net/index_old.html.

The current developers team at the Chair of Atomistic Modelling and Design of Materials, University of Leoben is highly motivated to provide a powerful innovative package to the electronic-structure community.
