"""M2Crypto client-side FTP/TLS.
This implementation complies with draft-murray-auth-ftp-ssl-07.txt.
Example:
>>> from M2Crypto import ftpslib
>>> f = ftpslib.FTP_TLS()
>>> f.connect('', 9021)
'220 spinnaker.dyndns.org M2Crypto (Medusa) FTP/TLS server v0.07 ready.'
>>> f.auth_tls()
>>> f.set_pasv(0)
>>> f.login('ftp', 'ngps@')
'230 Ok.'
>>> f.retrlines('LIST')
