Notes about the documentation
The first thing that you will notice is that the snapshot colours and fonts don't exactly match a default install. This is because I can't read the text with the default install, Lars must have a really good monitor, or I'm just getting old! I'll describe customization of the GUI later on, it's just matter of editing a CSS file anyway, so no rocket science.
I'm trying to document things following my understanding of them. This is also why some parts are not documented at all. I don't have this tool in production yet, although I plan to eventually pull the plug on the old system and pass to this one. Better documentation will hopefully come with some use.
