This script is designed for use in Mac-Labs. It should be placed in the Startup Items folder. It replaces the "Netscape Preferences" file (which is located in the "Netscape Δí" folder inside the "Preferences" folder) with a default version (located in a folder called "Default Files"). It also closes any open widows in the Finder, cleans up the Desktop, and empties the trash, readying the machine for the next user.
