First, make sure you're specifying the Bird protocol (it's the closest
to the RIPE protocol).  As soon as RIPE begins maintenance of the
RAToolSet we'll add the RIPE protocol specifically.  :)

Second, you'll need to modify the sources somewhat.  If you look in the
file src/irr/birdwhoisc.cc you need to add the following function:

// remove RIPE-style comments
static void stripRipeComments(Buffer &buf)
{
    // remove leading '\n' characters, if any
    while ((buf.getSize() > 0) && ((buf.getContents())[0] == '\n')) {
        buf.flush(1);
    }

    // remove comments at beginning of buffer
    while ((buf.getSize() >= 2) && ((buf.getContents())[0] == '%')) {
        char *contents = buf.getContents();
        char *eol = (char *)memchr(contents, '\n', buf.getSize());
        if (eol == NULL) {
            // no EOL, no comment to strip (yet)
            return;
        }
        buf.flush(eol-contents+1);
    }
}

This stips comments that begin with '%', which are RIPE-specific. This
needs to be called from the method BirdWhoisClient::getResponse().
You'll see the following line:

   } while (!found);

Change this to:

      stripRipeComments(*response);
   } while (!found);

Finally, you need to handle the case where no output except for comments
are returned.  Change the lines:

      if (found)
         break;

To be:

      if ((response->size == 2) &&
          (response->contents[0] == '\n') && (response->contents[1] == '\n'))
      {
         found = true;
      }

      if (found)
         break;

Compile, install, and you should be able to produce router configs.  If
necessary, I can send the entire file to somebody who doesn't feel
comfortable with editing the code by hand.
