Move the first sentence of the introduction a little back towards the
direction of my original version.  Specifically, "manage and control
complexity" is redundant, so move back to my "better manage software
complexity".  Also add back the "increasingly", as I mentioned in
email wanting to make this point specifically -- the utility of this
multi-platform pattern becomes more evident with scale and larger code
bases, which happens increasingly often now as computer systems get
larger.
