+
+    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.
