potrace 1.8-1 (lpia binary) in ubuntu hardy

 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 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), Xfig, Gimppath, and PGM
 (for easy antialiasing). Additional backends might be added in the future.
