Most of the remaining files are Maple worksheets. To open them you need
Maple 10 on your computer. If your browser is set up for it, Maple will
open the file automatically. If not, you will see a gibberish file.
Save the file as file.mw, start Maple, and open the file from the
location at which you saved it.
If you are using a Mac, save the file using the "Page Source" option
and then rename it as file.mw.
