navigating the pages on

the tree

Nearly every page on falls somewhere in a large (upside-down) tree structure. You can see the structure of the whole tree at the bottom of every page.

seeing where you are

There are two ways to find out where in the tree you are at the moment

  • using the tree at the bottom of every page
    • each branch and leaf - other than the current branch or leaf - in the tree contains a link
    • the name of the current branch/leaf is not highlighted (contains no link)
