The software that is the subject of this licence (“the Software”) is the body of source code, executable images, scripts, data files, test data, manuals and other documentation connected with the CRYSTALS Project. The function of the CRYSTALS software is to take single crystal X-ray diffraction data and extract from it a detailed description of the molecules in the crystal. The
software has two major parts: the underlying mathematical and crystallographic utilities written in FORTRAN and a graphical user interface written in C++.

CRYSTALS uses some functions from the LAPACK and BLAS mathematical libraries. See the LAPACK user’s guide, Anderson, E. and Bai, Z. and Bischof, C. and Blackford, S. and Demmel, J. and Dongarra, J. and Du Croz, J. and Greenbaum, A. and Hammarling, S. and McKenney, A. and Sorensen, D.
