+ * runPerfScript
+ * @scriptModule: module object with run and finish functions
+ *    and event handlers
+ *
+ * Runs a script for automated collection of performance data. The
+ * script is defined as a Javascript module with specified contents.
+ *
+ * First the run() function within the module will be called as a
+ * generator to automate a series of actions. These actions will
+ * trigger performance events and the script can also record its
+ * own performance events.
+ *
+ * Then the recorded event log is replayed using handler functions
+ * within the module. The handler for the event 'foo.bar' is called
+ * foo_bar().
+ *
+ * Finally if the module has a function called finish(), that will
+ * be called.
+ *
+ * The event handler and finish functions are expected to fill in
+ * metrics to an object within the module called METRICS. Each
+ * property of this object represents an individual metric. The
+ * name of the property is the name of the metric, the value
+ * of the property is an object with the following properties:
+ *
+ *  description: human readable description of the metric
+ *  units: a string representing the units of the metric. It has
+ *   the form '<unit> <unit> ... / <unit> / <unit> ...'. Certain
+ *   unit values are recognized: s, ms, us, B, KiB, MiB. Other
+ *   values can appear but are uninterpreted. Examples 's',
+ *   '/ s', 'frames', 'frames / s', 'MiB / s / frame'
+ *  value: computed value of the metric
+ *
+ * The resulting metrics will be written to @outputFile as JSON, or,
+ * if @outputFile is not provided, logged.
+ *
+ * After running the script and collecting statistics from the
+ * event log, GNOME Shell will exit.
