+<B>Q. How can I get high quality (antialiased) output?
+<P>
+The easiest thing may be to make the layout in Postscript (option <tt>-Tps</tt>),
+then run through <A HREF="http://www.cs.wisc.edu/~ghost/">Ghostview</A> with
+antialiasing enabled. The important command line options are
+<tt>-dTextAlphaBits=4 -dGraphicsAlphaBits=4</tt>
+(4 is the highest level of antialiasing allowed - see the
+<A HREF="http://www.cs.wisc.edu/~ghost/doc/GPL/8.15/Use.htm">Ghostview documentation</A>).
+The full command line to render a raster could be something like:
+<pre>
+gs -q -dNOPAUSE -dBATCH -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -sDEVICE=png16m -sOutputFile=file.png file.ps
+</pre>
+<P>
+On Mac OS X, the <A HREF="http://www.pixelglow.com/graphviz/">pixelglow</A> port
+uses Apple's Quartz renderer, which enables antialiasing. (The downside is
+that you can't run Pixelglow Graphviz as a web server or other background
+process if your Mac has 3D graphics, because Quartz wants to get this resource
+to accelerate its rendering.)
+<P>
+On the Linux bleeding edge, Graphviz can use the new <A HREF="http://www.cairographics.org">cairo</A>
+back end, which has antialiased rendering. This requires installing cairo, which
+is not part of graphviz itself. Cairo can be compiled from source and binary RPMs can be found
+for Fedora Core 4. It is believed that Cairo will be part of FC5 and may enable
+this back end if it is already installed.
+<P>
<B>Q. I can only get 11x17 output.</B>

It's not us! It's probably your printer setup. If you don't
