Okay, having now taken a look at the script, I have to agree -- a second
script is the way to go.

If I might offer some constructive criticism about the script as it sits
today, though:

   * The script should call sys.exit(1) at the end of "except
     ImportError" block

   * Add a --max-items option.

   * --revision could take a range, like the 'svn' client does.

   * Lose --url, and add --url-template, which is a URL with replaceable
     fields, such as:


     Dan Rall probably thought he was being helpful when he removed the
     mentioned of "viewcvs" from the --url description, but the new
     text implies a generality of the URL format which frankly isn't there.

   * Come up with decent default values for options for which
     it makes sense to do so:

        --svn-path could default to nothing, meaning "look in $PATH"
        --rss-file could default to os.path.basename(self.repos_path) \
                   + ".rss"
        --revision could default to the youngest revision in the repos

     Alternatively, the script should validate input before trying to act
     on it. Today you get cryptic errors as the script tries to use
     uninitialized variables and the likes.

   * Lose --repos-path, and make it a command-line argument, not an option.
     In conjunction with the other changes mentioned here, that would mean
     that running this script could be as simple as:

        svn2rss.py \
          --url http://svn.collab.net/viewvc/{repository}/?rev={revision} \
