The nova.flagmappings files [5] defines a relationship of the displayed
table of options (the heading in the nova.headers file) and the options.
The group information can be specified as a prefix to the option,
e.g. database/backend database.

the "Description of conductor configuration options" table for example in
[1] (sorry no direct linking possible, feature perhaps?) , where a table
may contain options from multiple groups or namespaces.

I have been looking into this process at present in free time to understand
and see how docs are generated. From my discussion with Gauvain it is both
manual and time consuming.

table or tables.  There is a 1 to n mapping of option to table, expressed
as one line in the file. The nova file has no example, cinder is a place to
look at.
