 ### File and Function Names
 
 Configuration is loaded using loco.  Specifically, by searching for `*.doco.md`, `.doco`, or `docker-compose.yml` above the current directory.  The loco script name is hardcoded to `doco`, so even if it's run via a symlink the function names for custom subcommands will still be `doco.subcommand-name`.  User and site-level configs are also defined.
