description         Library for FreeImage, a dependency-less graphics library

long_description    FreeImage is a library for developers who would like to \
                    support most popular graphics image formats. Some \
                    highlights are: extremely simple in use, not limited to \
                    the local PC (unique FreeImageIO) and Plugin driven!
