A very minor nitpick (that's about all I'm qualified for): in the section ...

Oh, it is not minor. What that really means was that it wasn't understandable.

It is a quite new idea, so it is useless for me to do without a good description -- otherwise people will never find it when they need it.

I just wish this part of finishing this module wasn't so much like a combination of pulling teeth and pulling a tractor for hundreds of meters. :-)

Sigh, I'll have to shuffle the document parts and add a description of the system to this document, too.
