/***
 * A class derived from TFTPRequestPacket definiing a TFTP write request
 * packet type.
 * 

* Details regarding the TFTP protocol and the format of TFTP packets can * be found in RFC 783. But the point of these classes is to keep you * from having to worry about the internals. Additionally, only very * few people should have to care about any of the TFTPPacket classes * or derived classes. Almost all users should only be concerned with the * TFTPClient class * receiveFile() * and * sendFile() * methods. *
