There are two versions of the template files. They both function the same, and contain the same thesis.tex file, but one has a lot more example content than the other. They are both available in zip or tar.gz format. There are two previews avaiable for each version.
All previews are available in postscript and pdf format.
If you are experienced using LaTeX, you can just get the basic files. These files will get you started, and aren't filled with a bunch of stuff that you will have to delete. If you would like to see more examples of different things you can do with LaTeX you can get the extended version. For other information please consult the contacts page.
