There's several ways to skin this cat. You could either define command-line
arguments that are parsed by the child script to get the settings it needs,
or you could use eval to execute the script's code in the lexical context of
the parent program. Please be aware, though, this can be dangerous since
variable settings, subroutines, etc., will remain after the script is
executed. You really need to do some careful management of internal
namespace to avoid problems.
That said, I would recommend that you move your code to be used in a more
modular manner, with whatever objects/interfaces needed being loaded upon
demand. Same effect, much safer method of execution.
