poldek hooks

[Caleb Maclennan]

Does poldek offer any hooks or way to trigger actions at any point?
For example are there pre/post transaction hooks that I could modify
to run something before and/or after any rpm action is taken? How
about an "on exit if any package installed / upgraded / uninstalled"
during the lifetime of the process? If so where is the best place to
find documentation on this?

On a related note, is it possible to globally add something to the rpm
%pre/%post/%preun/%postun macros?
