  Potrace 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), and the default output is one of several vector
- file formats.  A typical use is to create EPS files from scanned
+ PGM, PPM, or BMP), and the output is one of several vector file
+ formats.  A typical use is to create SVG or PDF 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.
