Let's order the fields from the most general to least: os name, os variant, os version, machine-parseable version details, metadata, special settings. I added section headers to roughly group the settings. The division is not strict, because for example CPE_NAME also includes the version, and PRETTY_NAME may too, but it still makes it easier to find the right name. Also split out Examples to separate paragraphs: almost all descriptions had "Example:" at the end, where multiple examples were listed. Splitting this out to separate paragraphs makes the whole thing much easier to read. Add missing markup and punctuation while at it. About - If not set, defaults to <literal>NAME=Linux</literal>. + If not set, a default of <literal>NAME=Linux</literal> may be used. and similar changes: in many circumstances, if this is not set, no value should be used. The fallback mostly make sense when we need to present something to the user. So let's reword this to not imply that the default is necessary.
