OK, this is the get page code, and tree at the bottom of the
www.hklc.com/midgard_manual
It would need some work to merge with the current news code -
eg. change the way that articles are got based on their name - this would need
more work to map name->article
anyway - It will create a tree navigation - and should be reasonably commented
so you can understand what to do with it....
It may not be the best solution to the problem :) - eg. most flexible....
