Where is mariadb.cnf config file variables, and there meaning?

I cannot find any list of all mariadb.cnf config file options, and their meanings.

I can get this for mysql. For virtually every other DB product I look at. But not mariadb?

I suspect that this is just poor website design, but:

- I tried Googling - I tried Googling with site:mariadb.com + mariadb.cnf - I looked at all the categories, and sub categories for my mariadb version, on your doc site, and nothing mentions the config file - There is no manpage (debian) which seems to match this - Searching for 'mariadb.cnf' on your site, yields no joy

If you have documentation on mariadb.cnf, no search for "mariadb config file", and half a dozen variations, yields fruit. No searches for the precise name (mariadb.cnf) yields fruit. There are all sorts of categories on the docs page, such as "optimization' and so on, but nothing about just the plain config file, with all its options, anywhere.

Help.
