If this is t , the function argument to deliver is used as the application startup function.
If this is nil , no application startup function is called when the delivered image is started up.
The image exits immediately upon startup when :run-it is nil . Any :call-count report requested is still generated on exit.
This keyword can be useful if you want to look at the symbols in the image (with the keyword :call-count ) but cannot you actually run the application -- for example because the application links up to a database, but the database has not been started up. In such cases, set it to nil .
