* Since very early on in Telodendria's development, the configuration
* file has existed inside of the database. This API also offers
* convenience methods for extracting the configuration out of the
* database.

* This documentation does not describe the actual format of the
* configuration file; for that, consult
* .Xr telodendria-config 7 .
