I only use one heading at the top level for each file.
The file name (without the .rst extansion) is a shorthand for the heading at the top of each file.
I would like to use the file names, and only the file names in the navigation tree.
The navigation for a section would show its children, and possible grandchilren, down to some
configurable level.
It would also be nice for the navigation to also show all the ancestors above the current section; i.e.,
the position of the current web page in the documentaion tree (using the file names).
I currently do this with links at the top of each section; e.g.,
grand_parent > parent > current
where grand_parent, parent, and current are the corresponding file names and grand_parent and parent are links.
How do I do this using sphinx ?
