Return to zoolib.h CVS log

Up to [Development] / ltp / pan

MAJOR UPDATE:
	- pan can now run complex command lines like "mkfifo gffifo17; growfiles..."
	- I have rewritten zoolib.  Functionally it is the same, but the
	  code is much cleaner and makes more sense.
	- updated pan and bump with the new zoolib
