It should be applicable. The framework I sketched should be compatible with=

any object that is well represented by a simple bunch of properties, and a=
=20
history entry seems to be nothing more than a "tuple" of (name, url, commen=

rating, ...).

Should also be possible, if you apply it on a bunch of card objects with=20
properties suit, position, etc.

You can have a look at the code already, it's in trunk/playground/games/kol=
f-
ng/engine/*state*, but note that the documentation is not very extensive an=
d=20
that saving the complete undo stack is not yet implemented. (It currently=20
saves just the current states, but the extension to the complete stack shou=
ld=20
be trivial once I come to it.)
