This function converts the EPS commands to the equivalent Luxor commands and evaluates them immediately in the context of the current drawing.
 
 !!! warning
     
     This function is designed to extract just the coordinates of paths from an EPS
-    file. An EPS file can contain much more information about an image than just the
-    coordinates: there's image and pixel data, font data, linear color gradients,
-    and so on. These are not translated into Luxor functions. This function
-    interprets some of the EPS commands in a Cairo-generated EPS "Prolog"; EPS files created
-    by other applications will likely not contain this Cairo-generated Prolog, and
-    so won't be interpreted at all (or will go wrong in interesting ways).

-In the next example, an SVG file is placed and exported to an EPS file, then the EPS file is imported and placed on a new drawing with Luxor functions instead of EPS commands. It's placed at an angle for no good reason. When saved as SVG, the graphics will be in SVG format again. Some losses are to be expected!
+In this example, an SVG file `linnux.svg` is placed and exported to an EPS file `linux.eps`, then this EPS file is imported and placed on a new SVG drawing using Luxor functions instead of EPS commands, respecting the current scale and orientation.
