Hmm... I'm not sure if I have access. Guess I could try.

Let's go for a separate file.

The js side at first.. I can try some perl if you're desperate. :-)

Responding to previous email, some api thoughts:

How to do that:

Sounds like a simple hash function. There are several md5 solutions out
there in js.. the only problem is that the ID needs to be prefixed with some
letters to ensure a valid id attribute. Something like... ?
getLinkID(docuri, linkuri)
{
    return 'l'+md5(docuri+linkuri);
}

appendRow(table, rowid)

displayResult(message, cell)
displayLink(link, cell)

The last two are basically the same function?
displayMessage(message, cellid);

I haven't had time to code anything working, but I did manage to get a
checkout of the perl lib and I'll get it running from cvs here shortly so I
can actually get something done.
