Does work here. A very minor thing I forgot yesterday: the window of  
the potrace experimental i-Package in i-Installer has retained the  
title "autotrace tracing program".

An example of the outputs of autotrace and potrace on exactly the  
same input, with default settings in both cases, can be seen at  
<http://homepage.mac.com/bvoisin/FileSharing4.html>. autotrace is  
better at tracing curves (like rounded corners), but introduces  
curved artifacts otherwise (transforming lines of constant thickness  
into lines of varying thickness, for example). potrace is better at  
tracing straight lines, but has a tendency to miss curved lines  
(missing, in particular, rounded corners). Thus it seems autotrace  
would be better at calligraphy, and potrace at technical drawing.  
Eventually I chose potrace, given the output had to be polished  
afterwards anyway in Adobe Illustrator (by manipulating each control  
point manually, so that straight lines are indeed straight lines,  
rounded corners are indeed circular, etc.).
