[arch-general] Doing a Recompile of All Packages?

Hi, Not sure how to pull this off effectively, but I would like to do a recompile of the system and all it's installed packages. How does one do this with the asp package, as the abs package no longer exists? I imagine that it would be something along of getting the name of all the installed packages, doing an asp checkout $packagename and then doing the makepkg song and dance, but is there a more efficient way of pulling this off? Thanks, Hunter
