Getting rid of all the .rpmsave files

[redhat at barendse.to (Remco Barendse)]

Hi list!

After yum upgrade of my CentOS 4.0 to 4.2 x86_64 box I now have countless 
.rpmsave files, about 90% of them I never touched or are config/start 
scripts.

Does anyone have a neat script that will find all the rpmsave stuff in 
/etc and then prompts per file whether it can replace the original or not?

Somehow doing this all by hand doesn't seem a very attractive idea :)

Thanks!!
