No, but that wouldn't be that a big deal. The rest is automated :-)

From my FAQ:

Why do I get "multiple definitions of ..." errors when excluding the GUI 
or JCE?
That means that your code is using and thus pulling AWT/Swing or JCE 
into the binary. You have to either uncheck the "exclude GUI/JCE" box or 
change/delete your classes that need the libraries.

Yeah, right. Without JCE, it will be about 4.5mb. I only kick the 
objects containing classes with swing, awt, applet, print or imageio in 
the package name.
