+   * FTPFileEntryParser interface.  If that succeeds, a parser
+   * object of this class is instantiated and is returned;
+   * otherwise it attempts to interpret the key as an identirier
+   * commonly used by the FTP SYST command to identify systems.
+   * <p>
+   * If <code>key</code> is not recognized as a fully qualified
+   * classname known to the system, this method will then attempt
+   * to see whether it <b>contains</b> a string identifying one of
+   * the known parsers.  This comparison is <b>case-insensitive</b>.
+   * The intent here is where possible, to select as keys strings
+   * which are returned by the SYST command on the systems which
+   * the corresponding parser successfully parses.  This enables
+   * this factory to be used in the auto-detection system.
+   *
+   * @param key should be a fully qualified classname corresponding to
+   * a class implementing the FTPFileEntryParser interface<br>
