+=============
+
+in the example page, i send a url off to google charts to create
+the QRCode. NEVER EVER EVER EVER EVER do this. I do it cause for
+the example it doesnt matter, and if i find a better way of doing
+it i'll do it. BUT creating a qrcode on a page aint terribly easy.
+The point is, that QR code is a URL containing the tokens SECRET
+KEY and should remain secret. You can generate qrcodes anyway you
+like, BUT MAKE SURE ITS SECURE (i.e. never save them on the FS,
+and send them all over ssl).

 How?
