[DESTINATION] is optional and specifies the process and component where to send the command. The [DESTINATION] must be in this format:

 \process/componentName\

'process' can be a processName or a PID. If it's a processName, the command will apply to all processes with the same name. If it's a PID, it only apply to the process with the matching PID.

Both the 'process' and the 'componentName' can be replaced with an asterix ("*)" to mean all processes and/or all components.

If the [DESTINATION] is omitted, the default destination

\"*/*\"

is used and applies to all processes and all components. The [in] preceding the [DESTINATION] is optional and may be omitted.

A command can be sent to a process/component that doesn't exist yet. It'll be saved and applied to the process/component when available. This way, you can pre-configure processes/components before they are spawned, but it's only valid if the [DESTINATION] is a process name. Otherwise, the 'process' will be dropped."
