[[discuss persistence in relationship to functionality that Metakit and other toolsets provide]

[LV] When I see the word persistence, what I think of is the concept of
the state of an application being retained between execution.

For instance, on my Palm Pilot, there are games and other applications which,
if executing when I turn off the device, pick up at the same spot when 
I turn on the device again.

Even neater, some applications retain their state when another application
runs - for instance, if I am reading a particular Palm document, then pop over
to the calendar, when I return to the palm document reading application,
the same document is opened, at the sample chapter and paragraph, as when
I left.

I seem to recall some operating system that I've used in the past doing
similar things - remembering what applications I was running at the time
of log off, and not only restarting those apps, but opening the appropriate
documents, etc.  (''Perhaps you mean this: http://www.eros-os.org/  --[Setok]''?)


Is this the type of persistence that is being referenced here - a saving
of state between invocations?
