%description
    Potrace(TM) is a tool for tracing a bitmap, which means,
    transforming a bitmap into a smooth, scalable image. The input is
    a bitmap (PBM, PGM, PPM, or BMP format), and the default output is
    an encapsulated PostScript file (EPS). 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.
    Potrace can currently produce the following output formats: EPS,
    PostScript, PDF, SVG (scalable vector graphics), DXF, GeoJSON, PGM
    (for easy antialiasing of pixel-based images), Gimppath, and XFig.
    Additional backends might be added in the future. Mkbitmap is a
    program distributed with Potrace which can be used to pre-process
    the input for better tracing behavior on greyscale and color images.
