hook into rpm install/update/deletion of any package (for etckeeper)

[Till Maas]

Hiyas,

is it possible to hook into rpm in a way that an arbitray programm is run 
whenever a package is installed, updated or deleted?

I want to test etckeeper:
http://kitenet.net/~joey/code/etckeeper/
This programm creates a repository for /etc and keeps track of changes that 
are done there via package updates and therefore it needs to hook into rpm as 
far as I can see. Is it maybe possible to do this with something 
like %trigger?

Regards,
Till
