/***
 * There exists a large class of IETF protocols that work by sending an
 * ASCII text command and arguments to a server, and then receiving an
 * ASCII text reply.  For debugging and other purposes, it is extremely
 * useful to log or keep track of the contents of the protocol messages.
 * The ProtocolCommandEvent class coupled with the
 * {@link org.apache.commons.net.ProtocolCommandListener}
 *  interface facilitate this process.
