> 2. How did he get that nice output of the WxMaxima session?

He printed the session to a pdf file. On linux you can do that from
the print dialog. On windows you can install a virtual printer (I use
http://www.pdfforge.org/products/pdfcreator ). This enables you to
create pdf documents from any application which supports printing.

You need to enable Greek characters from the option dialog (on linux
you will need to have Unicode support in wxgtk). If %alpha prints the
Greek character but alpha does not, you need to update wxmaxima.
