XXE install howto

Fetch XXE at XMLminds download site. Choose the autoinstalling versions for Mac OS X, and follow the instructions, which are basically drag-n-drop into the the "Program" folder.

Run XXE, this will make a directory $HOME/.xxe4

Then, download the forrest support package. You will have a folder called forrest on your desktop after this. Move this folder to the correct place using this command in Terminal: mv $HOME/Desktop/forrest $HOME/.xxe4/addon/.. Press enter. XMLEditor will now have support for the forrest document format, and the next time you open a forrest document those documents will be shown using the installed stylesheets.
