As of version 1.1.5, novi includes source RPMs (SRPMs) in its output.
If a fair portion of your build tree is SRPMs – that is, your favorite repos don’t have prebuilt packages for your OS/hardware combination – this new version of novi will help weed out the newest source pacakges. In turn, then, you don’t have to build all of the SRPMs and then use novi to sort out the latest binary packages.
As always, you can grab this from the download area.
