Hi Alex,

Many thanks for making this available. I definitely need it as I work
on 2 different computers so am always at risk of using an older file
and losing my updates.

So far, I haven't actually set it working, as I am reading your
scripts and learning how you did it.

The button to save the irev file didn't work for me (no error, but no
file created), so I grabbed the text directly out of the custom
property, however it requires your html.irev include file. It may be
that the only relevant bit from that is the definition of hBR, in
which case that is an easy fix.

I'll you know how I get on.

Cheers,
Sarah
