/***

|
* 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 ProtocolCommandListener interface coupled with the
|
|
* {@link ProtocolCommandEvent} class facilitate this process.
|
|
* <p>
|
|
* To receive ProtocolCommandEvents, you merely implement the
|
|
* ProtocolCommandListener interface and register the class as a listener
|
|
* with a ProtocolCommandEvent source such as
|
|
* {@link org.apache.commons.net.ftp.FTPClient}.
