    I do want to make a distinction between data that describes the
    properties of the system (e.g. things you'd find in a schematic) vs data
    generated by applications.  My intended audience was the people
    generating the former.  Any ideas on what an outline that maintains that
    distinction and includes application generated data would look like?

    Yeah, this is definitely something I've been wanting to cover.  Any
    ideas on how to make this easy for someone to do?  For example we have
    the anti-patterns document with a template - if we have a similar best-
    practices document with a template would that help?  I'm not so sure
    because the anti-patterns document hasn't gotten much traction
We can have a separate document or section in a document which will talk
about runtime configuration data type and its targeted location. Infact we 
can have a predefined variable for these like $systemdir. And meson will have
definition of these data input. We can also give example of meson file as how
it will be included for any project.
