Replicating a package set on a new machine

["Paul M. Foster via arch-general" <arch-general@xxxxxxxxxxxxxxxxxxx>]

Folks:

Assume I've installed a bunch of packages manually on machine A. Now I 
want to install those same packages-- not manually-- on machine B. I can 
have pacman tell me what packages are installed on machine A. Now, can I 
take the package list from machine A and, in an automated way, have 
pacman then install those packages on machine B? If so, how?
