To clear only old packages from cache

[speedyx]

It's a very useful method the entropy's one of keep all the versions of packages until I manually clean the cache.
But now that I don't need downgrading I want to keep in the cache only the latest version of packages, in /var/lib/entropy/client/packages...
Have you any script or suggestion to clear only the old versions of packages from cache and keep the latest ones?

the features you ask is similar to "eclean-distfiles" for gentoo user (tool to clean /usr/portage/distfiles)



I hope develeper (lxnay) consider this. It can be interesting.
