Ok, I guess I’m just about ready to try this thing out.
Copy the contents of the zip into a directory of your choice and run it using:
Windows: doubleclick gtkwordbuilder.exe.
Mac/Linux: in a terminal, run the command ‘mono gtkwordbuilder.exe‘
You will need an install as well. On the mono web page, you can find instructions for your operating system: http://www.go-mono.com/mono-downloads/download.html
Windows users will be able to run this with GTK# for .NET, a pretty small download.
I’d love to hear about your experiences with trying this version out on non-windows systems.
