Instead of using pacman,I use pacman-color.
Instead of using pacman-color, I use powerpill.
Instead of using powerpill, I use yaourt.
Well, that’s the chain of wrappers around pacman I use:
yaourt->powerpill->pacman-color->pacman
This provides colorized output and parallel (thus faster) package downloads.
Simply change in /etc/yaourtrc:
PacmanBin = /usr/bin/powerpill
and in /etc/powerpill.conf:
PacmanBin = /usr/bin/pacman-color
