description         Generic Image Processing Library for C++
long_description    VIGRA stands for \"Vision with Generic Algorithms\". \
                    It's a novel computer vision library that puts its \
                    main emphasis on customizable algorithms and data \
                    structures. By using template techniques similar to \
                    those in the C++ Standard Template Library, you can \
                    easily adapt any VIGRA component to the needs of your \
                    application, without thereby giving up execution speed.
