Original work by Carlo "carlocci" Bersani with additions by
Xavier Chantry and Allan McRae
This script rebuilds an already installed package using metadata
stored into the pacman database and system files. Replaces the
outdated re-pacman script
Signed-off-by: Allan McRae

I finally had a while to fix the permissions issue and to include fakeroot

This is the patch to the commit Allan made
