<!-- Proof of concept of running cool.html in an iframe. Also
shows how to, from outside the iframe, invoke Python scripting in
the underlying LibreOffice instance that manipulates the document
being edited.
This demonstrates using the Python InsertText.py and Capitalise.py
scripts from javascript across iframes.
