description         Transform bitmaps into vector graphics

long_description    Potrace is a utility for tracing a bitmap, which means, \
                    transforming a bitmap into a smooth, scalable image. \
                    The input is a bitmap (PBM, PGM, PPM, or BMP), and the \
                    default output is one of several vector file formats. A \
                    typical use is to create EPS files from scanned data, \
                    such as company or university logos, handwritten notes, \
                    etc. The resulting image is not "jaggy" like a bitmap, \
                    but smooth. It can then be rendered at any resolution.
