[ESS] What is easiest way to add an 'S+7' command?

[dstivers at mdanderson.org]

I too am in the position of using version 6 sometimes and version 7
sometimes; I thought about using S+3 or S+4 to start version 7, but aren't
there some differences in the way that ESS handles S+3, S+4 and S+6?

At present, I only have access to a single license of S+7, but virtually
unlimited S+6, so I usually fire up S+7 outside of xemacs when I need to
use it.

Main Splus environment: SuSE 9.3 64 bit, ess version 5.2.10, xemacs
21.5.18, Splus 6.2.1 or 7.0.3
