Sorry, I forget the synax of commands sometimes.  Actually, I'm
wondering if Aap will become simpler to use when the Aap commands would
take arguments like the Unix commands.

You could set a variable in the block where the file is copied, and then
at the "finally" target check for it:

	didit = 0

	didi : dodo
	  :copy {f} $source $target
	  didit = 1

	...

	finally:
		@if _no.didit:
		   :sys run the command
