	`script`::
	
	Executes an external script or binary when the profile is loaded or
	unloaded. You can choose an arbitrary executable.
	+
	IMPORTANT: The `script` plug-in is provided mainly for compatibility
	with earlier releases. Prefer other *TuneD* plug-ins if they cover
	the required functionality.
	+
	*TuneD* calls the executable with one of the following arguments:
	+
	--
	** `start` when loading the profile
	** `stop` when unloading the profile
	--
	+
	You need to correctly implement the `stop` action in your executable
	and revert all settings that you changed during the `start`
	action. Otherwise, the roll-back step after changing your *TuneD*
	profile will not work.
	+
	Bash scripts can import the [filename]`/usr/lib/tuned/functions`
	Bash library and use the functions defined there. Use these
	functions only for functionality that is not natively provided
	by *TuneD*. If a function name starts with an underscore, such as
	`_wifi_set_power_level`, consider the function private and do not
	use it in your scripts, because it might change in the future.
	+
	Specify the path to the executable using the `script` parameter in
	the plug-in configuration.
	+
	.Running a Bash script from a profile
	====
	To run a Bash script named `script.sh` that is located in the profile
	directory, use:
	
	----
	[script]
	script=${i:PROFILE_DIR}/script.sh
	----
	====
