			* '''stdoutValue'''<br>the stdout type-converted as per datatype. That means that if the stdoutValue pin is of type Number, expecco will try to convert the generated output (which is a string initially) to a number, and report an error if it fails to do so. Likewise, if the pin's type is Boolean, it will look for "true" or "false" (in either case). If the generated output is more complicated or consists of multiple lines, you will have to extract the relevant data using either a regular expression matching action, or by defining a customized extract action.

			===== Input Pin: Do not Log Pin Value =====
			The value is not recorded in the log. Set this for secret data or huge data values which would otherwise make the activity log unacceptably large.

			===== Input Pin: Limit Input Basket Size =====
			Set the number of values which are queued in the pin's input basket.
			If the basket is full, a producing step will be suspended until it gets emptied.

			Be reminded, that for every incoming pin a new activity is created which executes the action;
			in a producer-consumer situation, the producer may easily outrun the consumer unless the basket size is limited. By default, the bssket size is unlimited.
