+# A simple FTP client.
+#
+# The information to write this program was gathered from RFC 959,
+# but this is not a complete implementation!  Yet it shows how a simple
+# FTP client can be built, and you are welcome to extend it to suit
+# it to your needs...
+#
+# How it works (assuming you've read the RFC):
+#
+# User commands are passed uninterpreted to the server.  However, the
+# user never needs to send a PORT command.  Rather, the client opens a
+# port right away and sends the appropriate PORT command to the server.
+# When a response code 150 is received, this port is used to receive
+# the data (which is written to stdout in this version), and when the
+# data is exhausted, a new port is opened and a corresponding PORT
+# command sent.  In order to avoid errors when reusing ports quickly
+# (and because there is no s.getsockname() method in Python yet) we
+# cycle through a number of ports in the 50000 range.
