Notes:

• Single scripts have been renamed by adding '.txt' so you can view them online (remove '.txt' before using).
• Sets of scripts (like Flac_Jacket) are tar/gzipped.
• To extract the tar files after download, use tar xvf filename.tar or tar tf filename.tar to display the contents.
• To extract the tgz files after download, use tar xzf filename.tgz or gunzip filename.tgz;tar xf filename.tar
• Make sure the script is executable. You may need to chmod 755 (or whatever) so it is executable.
• Check for any variables that may need changing, edit to match your needs.
