! 4: This defines execution chains.
! 5: The first application for this is building initialization chains:
! 6: Think of many modules or program parts, each of it with some specific
! 7: initialization code. If we hardcode the initialization routines into a
! 8: "master-init" we will get unflexible and are not able only to load some
! 9: specific modules...
! 10:
! 11: The chain is basicaly a linked-list. Define a Variable for the head of
! 12: linked-list. Name it "foo8" or "foo-chain" to indicate it is a execution
! 13: chain.
! 14:
! 15: You can add a word to the list with "' my-init foo8 chained". You can
! 16: execute all the code with "foo8 chainperform".
