With apt-rpm you have the possibility to replace a package inline from a 
repository, you can do this with:

 	apt-get install --reinstall <package-name>

This is useful if you damaged files that belonged to an installed RPM 
package without having to uninstall all the packages that depend on it as 
well.

Under the hood it is the same as:

 	rpm -Uhv --replacefiles --replacepkgs <file-name>

The --reinstall feature is also useful when during CentOS QA packages are 
being updated with the exact same version-release. Or when you want to 
convert a RHEL into a CentOS or the other way around.
