Fs2 open on Linux/Data Installation script

Warning: Again, please double check and understand the commands you run as root. A single typo could destroy your data. Remember, with great power comes great responsibility.

The following script will extract the necessary files to the TMPDIR and install them to the specified FS2DIR from the CDROM, prompting you for each disk. These values may need to be changed for your system. You may need to run this script as root and don't forget to chmod +x it.
