 * to use for its data.  Valid Content-Transfer-Encoding values specified
 * by RFC 2045 are "7bit", "8bit", "quoted-printable", "base64", and "binary".

 * <blockquote><pre>
 *  public class Base64FileDataSource extends FileDataSource
 *					implements EncodingAware {
 *	public Base64FileDataSource(File file) {
