I've just created a wiki article to describe what a bounding box is,
essentially its a set of 4 coordinates, which describe the edges of a
box. You can get the figures by using the 'Export' tab on the main
website, clicking on "Manually select a different area" and drawing
the box on the map. Then use the figures given in this order:
The other numbers you may wish to change are those before the
description (eg: 1, 12, "Muenchen"), these are the zoom levels at
which the tiles will be generated.
