It depends on how complex the data is, but the simplest approach is to use the
GlobalVar constructs. The first two examples in "goodies/hooks.txt" show how to
do it. The first hook is a StartupHook which reads the file and initialises the
GlobalVar's, while the second hook uses the GlobalVar data to manipulate the
packet contents.
