dS)*aSAn FTP client class and some helper functions.

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
total 9

A nice test that reveals some of the network dialogue would be:

    To create a connection, call the class using these arguments:
            host, user, passwd, acct, timeout

    The first four arguments are all strings, and have default value ''.
    timeout must be numeric and defaults to None if not passed,
    meaning that no timeout will be set on any ftp socket(s)
    If a timeout is passed, then this is now the default timeout for all ftp
    socket operations for this instance.

    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.

         - source_address: a 2-tuple (host, port) for the socket to bind

        If the transfer is active, send a port command and the
        transfer command, and accept the connection.  If the server is
        passive, send a pasv command, connect to it, and start the
        transfer command.  Either way, return the socket for the
        connection and the expected size of the transfer.  The
        expected size may be None if it could not be determined.

        Optional `rest' argument can be a string that is sent as the
        argument to a REST command.  This is essentially a server
        marker used to tell the server to skip over any data up to the
        given marker.

Zdd�ZdS)�FTP_TLSa�A FTP subclass which adds TLS support to FTP as described
        in RFC-4217.

        Connect as usual to port 21 implicitly securing the FTP control
        connection before authenticating.

        Securing the data connection requires user to explicitly ask
        for it by calling prot_p() method.

        Usage example:
        >>> from ftplib import FTP_TLS
        >>> ftps = FTP_TLS('ftp.python.org')
        >>> ftps.login()  # login anonymously previously securing control channel
