-/***
- * The NNTP class is not meant to be used by itself and is provided
- * only so that you may easily implement your own NNTP client if
- * you so desire. If you have no need to perform your own implementation,
- * you should use {@link org.apache.commons.net.nntp.NNTPClient}.
- * The NNTP class is made public to provide access to various NNTP constants
- * and to make it easier for adventurous programmers (or those with special
- * needs) to interact with the NNTP protocol and implement their own clients.
- * A set of methods with names corresponding to the NNTP command names are
- * provided to facilitate this interaction.
- * <p>
- * You should keep in mind that the NNTP server may choose to prematurely
- * close a connection if the client has been idle for longer than a
- * given time period or if the server is being shutdown by the operator or
- * some other reason. The NNTP class will detect a
- * premature NNTP server connection closing when it receives a
- * {@link org.apache.commons.net.nntp.NNTPReply#SERVICE_DISCONTINUED NNTPReply.SERVICE_DISCONTINUED }
- * response to a command.
- * When that occurs, the NNTP class method encountering that reply will throw
- * an {@link org.apache.commons.net.nntp.NNTPConnectionClosedException}
- * .
- * <code>NNTPConectionClosedException</code>
- * is a subclass of <code> IOException </code> and therefore need not be
- * caught separately, but if you are going to catch it separately, its
- * catch block must appear before the more general <code> IOException </code>
- * catch block. When you encounter an
- * {@link org.apache.commons.net.nntp.NNTPConnectionClosedException}
- * , you must disconnect the connection with
- * {@link #disconnect disconnect() } to properly clean up the
- * system resources used by NNTP. Before disconnecting, you may check the
- * last reply code and text with
- * {@link #getReplyCode getReplyCode } and
- * {@link #getReplyString getReplyString }.
- * <p>
- * Rather than list it separately for each method, we mention here that
- * every method communicating with the server and throwing an IOException
- * can also throw a
- * {@link org.apache.commons.net.MalformedServerReplyException}
- * , which is a subclass
- * of IOException. A MalformedServerReplyException will be thrown when
- * the reply received from the server deviates enough from the protocol
- * specification that it cannot be interpreted in a useful manner despite
- * attempts to be as lenient as possible.
