In addition to the internal settings, tinyMediaManager also supports to set some low level runtime parameters through the launcher configuration. The launcher configuration (launcher-extra.yml) can contain either Java JVM parameters or some special parameters for tinyMediaManager itself. The launcher configuration must be in the form

javaHome: "custom Java home"
- "JVM - parameter"
- "environment option"

The sections of the configuration is as follows:
