Can you give me an example? You should just download the file and unzip it into a folder on your desktop (or other temporary location). Right now the code will just use the directory name where the source files are. If there are no folders within the zip file itself, just create a new folder and unzip them into there.

In the future, I'm thinking about switching over to a wizard interface and asking the user what they would like to call the scenery before it gets installed.
