ftplib question: how to upload files?

[python at sarcastic-horse.com]

Hi:

I want to write a procedure to automatically upload some files for me, but
I'm getting stuck.  Before I write my own gruesome put() function, I
wanted to check if there is an easier way.

Here's what I can do so far:
>>>import ftplib
>>>conn = ftplib.FTP('ftp.example.com')
>>>conn.login(user='userid', passwd='passwd')
>>>conn.cwd('/var/www/html/incoming')

What do I do to send files?

I have three files I want to upload, but I'm not sure what to do.  I hoped
to find a ftplib.put() method, but it looks like ftplib is a low-level
interface.

All help is welcome.
