I created the Help wiki entry for editing XML. It's pretty basic, so feel free to add or amend (or correct mistakes):
Excellent job Kjeld. You have inspired me to want to do a wiki page for Ravenloft.
Very nice - something I struggled with for sure - hmmmm
Great start! Thanks Kjeld!
Good job! Maybe Ozy can add a summary of his tools there.
It would be really nice to, eventually, build in a bit of an explanation of python and how it can be used to automate the editing of WarGear XMLs. We could also work to build a library of scripts to perform different tasks, akin to the back-end of what Ozy's Advanced WarGear XML Editor does. That way, people with a bit more coding chops can add to and customize the great work that Ozy has already done, if they want to.
