This is the Cologne Laue Indexation Program or short CLIP It is a program to index and refine laue exposures. It can do simulations as well as index and refine from spots and zones marked on a Laue photograph. Afterward the rotations to obtain a special orientation could be calculated for arbitary goniometer configurations. The program is written in the C++ programing language and the cross platform toolkit Qt. It runs on Windows, Linux and MacOS X. I would like to thank Gregory Tucker for his contributions to the Multiwire-Import filter.
