	Just wait, no zombies! (yah, little unix humor)

	There are several IPC modules which make interacting with other
processes less work. If you aren't interested in a full framework I would
suggest investigating a couple (e.g. IPC::Open3, IPC::Run, Expect, etc.).
	Of course it still helps to have a base understanding of how
processes are spawned/reaped on your O/S.
