/**
     * Parses a line of an NetwareFTP server file listing and converts it into a
     * usable format in the form of an <code> FTPFile </code> instance.  If the
     * file listing line doesn't describe a file, <code> null </code> is
     * returned, otherwise a <code> FTPFile </code> instance representing the
     * files in the directory is returned.
     * <p>
     * <p>
     * Netware file permissions are in the following format:  RWCEAFMS, and are explained as follows:
     * <ul>
     * <li><b>S</b> - Supervisor; All rights.
     * <li><b>R</b> - Read; Right to open and read or execute.
     * <li><b>W</b> - Write; Right to open and modify.
     * <li><b>C</b> - Create; Right to create; when assigned to a file, allows a deleted file to be recovered.
     * <li><b>E</b> - Erase; Right to delete.
     * <li><b>M</b> - Modify; Right to rename a file and to change attributes.
     * <li><b>F</b> - File Scan; Right to see directory or file listings.
     * <li><b>A</b> - Access Control; Right to modify trustee assignments and the Inherited Rights Mask.
     * </ul>
