Human readable and line by line parsable are pretty much mutually
exclusive - try expressing any complex structure in Xresources. However
its easy to have a format which can be parsed line by line, and produced
from a human writable format.
One such example is RDF/NTriples, which is a simple ASCII format that can
be parsed with a trivial regex, scanf or similar. It can be generated using
commonly available tools from RDF/N3 or RDF/XML which are human
readable/writable. It looks like:
<foo:a> <foo:b> <foo:c> .
<foo:a> <foo:d> "e" .

Yes, but xrm misses most of the desirable feaures of metadata languages
(agreed semantics, extensibility and so on). We could just use the syntax,
but its pretty complex for non-X11 apps that want to parse it.
