Purpose: This is an individual project to implement a network application: an ftp client program based on the Internet Engineering Task Force RFC 959 protocol.
--------------------------------------------------------------------------------------------------------------------------------
Notes: The file transfer protocol (ftp) is defined in a 1985 IETF [plain text] document, RFC 959. It is highly recommended that you read this document, and
understand the FTP functions (described in Section 4.1), especially: USER, PASS, SYST, PASV, LIST, RETR, STOR, QUIT
