We upload our nightly builds to our devpi server. There are a lot and the files are big so I like to delete files over 30 days old (plus they are no longer useful at that age).

What is the best way to do this in an automated fashion with devpi? Using the devpi client to do it manually it not appealing. 

I could script something "devpi remove -y pkgname>=2014.6.dev1;<2014.7.dev1" that would remove all 30 files 2014.6.dev1...2014.6.dev30?

Any other ideas?

Cheers
Craig
