[arch-multilib] placement of repo in pacman.conf

[Matthew Monaco]

Where are you guys putting multilib in pacman.conf? My instinct was last, but I 
see while there are still duplicates in community, it really needs to be moved 
up a little.

That being said, might a better situation (in an ideal word) be to develop 
"multilib" as a sort of psuedo alternative architecture, rather than a repository?
