hey, nice idea, can come very handy in some situations

though i took your description wrong the first time i read it.
you say it works according to the LIFO idea, yet in your last
paragraph you say it keeps the last one and removes the older one

you keep the last one so the first one gets deleted first.
that would be FIFO no? or LILO as both are the same in this situation.

other than a bug in your description this package seems to work well so far
thanks!
