Config files to load are set using the -c flag on command line. If no flag is given, a beat and OS-specific default file path will be assumed.

You can specify multiple configuration files by repeating the -c flag. You can use this, for example, for setting defaults in a base configuration file, and overwrite settings via local configuration files.

In addition to overwriting settings using multiple configuration files, individual settings can be overwritten using -E <setting>=<value>.
