The command is simply: "pacman -S ldc" and the Arch Linux logo can be found here: http://www.archlinux.org/art/
...on the 'Downloads & Tools' page, it might be nice to list the
install command for Arch Linux as well. Although I doubt any Arch
users won't first try a pacman command, it's very well supported
on Arch Linux official repos and it might be nice to advertise
that fact. LDC on Arch is up-to-date (version 2.060), and a very
good compiler, especially with the release of LLVM 3.1's
auto-vectorization.
