+     "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 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.")
