repo check tools

[Peter Astakhov <astakhovp elinar-broiler ru>]

Hello!
I am interested in tool, which can remove or generate list of unused 
packages in the repo catalog.
For example, now in Fedora Extras exist package 
wesnoth-1.0.2-4.fc6.x86_64.rpm and wesnoth-1.2-1.fc6.x86_64.rpm
Same situation with a lot of packages For example:
ls selinux-policy-targeted-*
selinux-policy-targeted-2.4.1-3.fc6.noarch.rpm 
selinux-policy-targeted-2.4.3-2.fc6.noarch.rpm 
selinux-policy-targeted-2.4.6-1.fc6.noarch.rpm
selinux-policy-targeted-2.4.2-3.fc6.noarch.rpm 
selinux-policy-targeted-2.4.5-3.fc6.noarch.rpm 
selinux-policy-targeted-2.4.6-7.fc6.noarch.rpm
selinux-policy-targeted-2.4.3-10.fc6.noarch.rpm 
selinux-policy-targeted-2.4.6-13.fc6.noarch.rpm

As far as I understand, 7 packages are obsoletes an d I can remove it.

Is tool for this management exist?
