:In retrospect, it makes sense why "r+" is one that raises IOError: it
:means that we're assuming that the file exists and is good for reading and
:writing.  But like the regular "r" mode, if the file isn't there, then it
:will raise an IOError.

This is how I would have thought things work, and that is obviously what the
docs say. But, then I just don't get why I was getting this error:

  File "gypsymail.py", line 117, in PrintErrorToLogFile
    logfile = open(logfilename, 'a+')
IOError: (2, 'No such file or directory')

In any case, the script seems to be working fine, now. I changed that line of
my program to 
    logfile = open(logfilename, 'a')

since I'm only going to write to the file, anyway, and I don't need the a+
functionality. It now seems to create the file, when the file doesn't already
exist. Beats me, what the problem was before.
