Based on RFC 959: File Transfer Protocol (FTP), by J. Postel and J. Reynolds
Example:
>>> from ftplib import FTP
>>> ftp = FTP('ftp.python.org') # connect to host, default port
>>> ftp.login() # default, i.e.: user anonymous, passwd anonymous@
'230 Guest login ok, access restrictions apply.'
>>> ftp.retrlines('LIST') # list directory contents

To create a connection, call the class using these argument:
host, user, passwd, acct
These are all strings, and have default value ''.
Then use self.connect() with optional host and port argument.
To download a file, use ftp.retrlines('RETR ' + filename),
or ftp.retrbinary() with slightly different arguments.
To upload a file, use ftp.storlines() or ftp.storbinary(),
which have an open file as argument (see their definitions
below for details).
The download/upload functions first issue appropriate TYPE
and PORT or PASV commands.
